google s2nome blog and he talks about the next gen moba
-small hero pool (50 max)
-heroes with more skills yet can't max every single one (example, 8 skills with 4 levels each, but you only get 16 skill points)
-d2 type inventory screen (to prevent new players from buying 2 boots), maybe a slot for orbs effects and wards
-reduce hard carries and ward bitch heroes by making every hero closer to the middle of those extremes
