For months folks have been saying that Deckard Cain should make his way into Heroes of the Storm. I even joked about it with a senior developer once upon a time, who noted that while he would be difficult to implement, he could work.
Well Blizzard has implemented everything they've needed to, as this not April Fools Joke character is really real, has his own talent list, and is accompanied by his new look above.
Deckard Cain will play a support role, and is instantly buffed if he's near another allied hero (10 armor, basic abilities recharge 50% faster). He can toss healing potions (Q), the Horadric Cube (W) for damage, and unfurl scrolls of sealing (E) that do damage and root.
I'm sold on the concept, but we'll likely be able to test him out on the PTR soon enough to see if he actually works in action. I love the idea of throwing out five stock healing potions with a 50% faster cooldown (that's a pot every 1.5 seconds) -- it's a decidedly more active support playstyle than a lot of other similar characters.
