There are currently 93 heroes in HoN.
New content is important in a company for revenue and for interest to continue however I'm guessing there will be a time when S2 and the community decide that there are "enough" heroes to stop bringing in new ones.
I would like to ask what S2's goal is for the total number of heroes in the pool; is this a defined number or is the goal just to add more variety via more heroes?
The hero selection display in-game and found under the "Heroes" button on the website have a limited number of heroes in each section. Is this to hint at a number S2 wants in each category before considering the game 'complete'?
Sorry Macro, it's just too good.
There is no foreseeable end to the implementation of heroes.
And, as stated before, the hero display can ALWAYS be expanded!
