We need a sixth installment of Heroes, they haven't exhausted the potential yet. Improve the graphics, make the skill system even more well-thought-out, and so on – there's no limit to improvement!
and get another expansion that lasts for a month. We've already seen all of this.
No, no matter what you say, but there's nothing new. Many abilities in the game are already contrived.
I think something like the fourth game in spirit and innovation would bring something new... but if it's just another third or fifth game, it will be bad. People can't keep eating the same thing forever.
