Currently Celene here is the only hero in Soulkeep. To put these numbers in perspective, her ranged attack is a little bit below that of an Ivory Tower though she attacks faster. I haven't looked at every tower at every level to compare, but I believe she has the highest single target damage per second in the game before upgrades when she's firing at range. Once something gets on her and forces melee the damage drops considerably as you can see. Up close and personal she does single target damage per second equal to what an aoe tower like Charnel Pit does.
I believe it can be assumed that Celene was/is not intended to be the ONLY hero in Soulkeep. She may end up the only legendary hero, but do you think Double Coconut designed the massive central Hero section of the UI for a card that only printed less that 500 copies? Surely not. So the questions then become what kinds of other heroes does DC release and when?
Last point first, when should DC try to release a new hero? I know that right now basically everyone who doesn't own a Celene would love something, likely anything even, to fill that glaring hole in their deploy screens. However is now the right time to release 1 when less than 300 accounts seem to be playing currently? Should DC maybe consider a common or rare hero that doesn't have a set sale time limit, it is just always available for purchase in the store? What is everyone's thoughts on the when of things?
As to the what here is my idea for a common or rare "starter" hero, Tank. Tank(lame name yes) would be a melee hero who blocks the entire width of the lane they are placed in. All mobs are blocked from progressing beyond Tank until Tank is killed. Tank would have 2x the health, and equal melee damage(maybe slightly more?) compared to Celene but no ranged attack. Would anyone use that? Do you have thoughts on a different hero idea maybe?
