Honestly...not that far off for a two-year-old concept. Link to official Alexstrasza page. http://us.battle.net/heroes/en/heroes/alexstrasza/#?skin=dragon-aspect-alexstrasza

No luck on Ysera, but you were right about Alexstrasza!

I actually thought about the same thing when designing Malygos. The way that I justified it is that although there are a fair amount of Heroes that use alternative or no resource, it would be difficult or impossible to build a team without at least one Mana user (I don't know of any Healers that don't use mana) And even if QM throws together something like Illidan, Murky, Cho'Gall, Tracer...well there's always Aspect of Magic. So yeah, no-mana Heroes are definitely a weak spot in his kit, but...

Thanks for the compliment! And to answer your question, no, Arcane buffer would not be usable during Arcane Breath, because the way that channeled Abilities generally work (except for Morales, I guess) is that they silence all your others until you cancel.

I love this concept. I had considered designing a Colossus concept a while ago, and I think yours really hits the nail on the head of what I pictured it would be like, plus some.

Overall, I like this concept. HoTS could use some more Mages in it's roster! I do think your talent tree could use a little pruning though. I'm seeing a lot of talents that improve Basic Attacks, (Seasoned Marksman, Executioner, Nexus Frenzy, Giant Killer), and if she's supposed to be an Ability-based Hero like Kael or Jaina, then I don't think these synergize well with her intended playstyle. Also, I think both the cooldown reduction on Arcane Rebound and the passive Block effect of Avatar...

I think normally I would have done Ysera as a support, but A:My Alexstrasza concept is also a support and I wanted to diversify a bit, and B: I've seen someone else make a good Ysera support concept recently so I wanted to try and do something different.

Thanks, I hadn't noticed quite how powerful that was. I was counting on Heroes being able to escape before the full duration, but i guess that's not a guarantee.

I don't necessarily see that as a bad thing. Most support characters have one Heroic that is the obvious choice if they're the solo healer for their team, especially when going up against another support with a strong healing Heroic (Malf, Rehgar, LiLi, etc...).

Percentage-based healing seems inherently unbalanced. Numerically, you'd be doing more healing to the beefy Tank characters (and Azmodan), and less healing to the squishies (Li Ming, Jaina, Illidan...), which makes them too vulnerable. The 20% bonus from G'hanir's Blessing is alright, but Emerald Light, Dreamer's Breath and Emerald Vision (+ associated talents) should probably use flat values. Otherwise, I really like her CC abilities.
