May we please get a button or shortcut to add a level into health for all champs? It's tedious scrolling through champs and trying to level all their healths individually quickly.
One suggestion : Spread the DPS a little evenly around heroes so none are obsolete other than their abilities. I'd say give the healer an ability that gives other heroes 2%DPS of the strongest or whatever fits without throwing off damage/progression ratios.
