I have mixed feelings on this hero. I love the hands off, I hate the idea of wholly support (or almost nearly so). I can't fully go into detail as is obvious with the Elite ability, but other than that I'll toss my pennies out.
I feel that, though the support theme is there, a more focused theme could be used. Not specifically as I originally thought of as "Support towards the specific goal of death" but possibly a more specific form of support instead of how well rounded he is with: +Damage vs Enemies, -Damage to Allies, and -Speed to Enemies. As'll be seen with my comments I'm thinking maybe a specific goal should be put in mind, like...good at siege aiding, good at defending allies, good at buffing for small battles, good at specific buffs or whole army buffs, I don't know, things like that.
Doom Reverb - As with Grayl (Whom I've very little experience) I like the idea of having an ability to replace the attack, as long as its practical. In this case I enjoy how passive the damage dealing is. Its a very specific damage based on how a battle goes though, so I see the need for the other abilities to require aid to allies or hindrance to enemies, as they are needed wholly for Doom Reverb to work.
What if it were to work the opposite way? When it takes damage nearby enemies recieve X%? Or When it dies enemies nearby take X damage? With all the abilities of this hero (Minus the ultimate) aiding or hindering units in groups, having his sole way of dealing damage merely affect a single unit seems contradictory. I personally would prefer his damage to be AoE as that seems more supporting that taking down a single target.
Second Thoughts: What if perhaps, Doom Reverb was kept as is with its single target damage, yet had a spreading effect much like Eulalie, where it either spreads to all units in a small AoE, or spreads to any unit below X% health? Thus killing weaker units faster and causing Eulalie to spread faster (Which also may link into my ideas on Eulalie if I write them)
Icon of Dominance - Extremely basic support skill, I'm not sure if I like it or not. It feels almost too basic, moreso than his innate, which I feel should, if there to be one, be the most basic portion of the hero. Its exact aid to allies and harm to enemies seems best used in large scale battles, although more specifics would be needed, whether it be a small AoE, huge boost, and low cooldown; or large AoE, medium boost, and larger cooldown. Also, it would be nice to know if it could stack upon itself, thus bringing more into the use of it rather than plant and walk away.
Some thoughts as regarding it with Hollow's other skills; very effective with the innate and Eulalie, being able to cause catastrophe seems amazing, especially where the sole target suffers the most the quickest, I suppose I never thought of him as support to a swift finish, silly me. I feel it is complete in its own way, as basic as may be, no further comments really.
The Lost Sonata - Least favorite skill. As much as I enjoy the idea of defending allies, I feel this skill needs something else for a few reasons; I don't know this character's standing, how evil he is, how he thinks, I realize the Bane is not pure evil, but I wish to know where exactly magical defense stands in his head. Its a strange skill as well, magic damage is (roughly) half of the damage being dealt, so I guess this skill would be very helpful if X was of considerable amount, but that is up to debate. If X is large then it would seem as though this skill should be on for every major fire fight, cooldown also requires a part of this, as there are no (if I remember?) mana costing basic spells/abilities. Essentially he gives up mana buildup to half-save his allies (not so blunt but I hope thats what it is).
I guess I only feel it worth it if X is extremely high. Defense is nice at that large (I assume no mana gain = large sacrifice) but I almost don't feel as if this hero needs any major defensive abilities.
Echoing Eulalie - By far my most favored skill, and I see how it mixes well with Hollow's innate, but I still have mixed thoughts. I really,
really enjoy the thought of a rampant spell. Chaotic yet predictable in its spread. I also believe that its movement reduction is all that's needed for the spell (as do you :O). Overall I feel it to be the most complete spell, where my only idea would be as to have it a build up spell:
As Jhita's ability (the name is not coming to me) in DoE has its capability for massive build up damage, I believe this should as well. I realize I do not know the idea for how large X would be, but I feel that it would seem much better in terms of in play and lore-ish idea of a song-slinger who's "Echo" reverberates back stronger and stronger as it continues (Possibly illogical...) thus causing more and more pain/anguish/crippling sensation.
...and to the blunt of what I'm saying. X remains a small-ish number, but effective, and the buff stacks until a certain % or something.
Last Rites - No comment may be had for lack of knowledge.
[Known]
Last Breath Before Dying - Ah, such an amazingly imagined skill. My imagination loves it, though I'm sure we're both seperate on its exacts I feel I can see a bit of what you imagined. My comments though...
As I do not know the exacts about 3.00 (As I'm sure only Dusk and yourself are clued in on) I'm not sure how to comment. I realize how epic the ultimates are to be for 3.00, but I'm unsure as to how easily executed they should be. I guess because of this I can't comment too much on this skill, but I'll just toss in that I love it.
Ideas: As I said before I'm not sure about the two first skills (excluding his innate), so here are a few ideas I have for them as replacement rather than improvement (as stated) but because I feel that Icon is fitting for now, Sonata will be my only idea.
- Instant Cast AoE - Debuffs all units with the '' debuff. Whenever a unit with the debuff dies a counter is stacked onto all other debuffed units. When the debuff wears off all allies are healed by X for each counter and enemies are damaged for each counter. Cannot affect Hollow.
What this would give is a more destructive feel to the hero, yet retains his passive feel; and though he seems to feel very passive in theory'd playstyle, I believe this still adds to the thought required in playing him. It brings a closure to Eulalie in either form (Kao's or my own take), where with Kao's, it may take out all units causing the spread to cease, but death of the enemy is wanted right? With my take, it brings the slowest, and thus last enemy, to a painful final thrust of death, mirroring his ultimate nearly, less epic though...
Last Thoughts: Sorry for my garbled typing, I may go through again to make it less wordy. I enjoy the idea of the hero. Passive support requiring active thought, a good balance that may require tweaking to be fully birthed.
