the flexibility problem

[cabal core]

when i am plying the beta version.i feel that there are low flexibility on some heroes............(e.g witch doctor)when i am casting a summon spells it takes about some time to click off to the icon....when i wanted to cast fire boom i just press the hotkey>ESC to exit the summon skill menu and it just pop out the inventories..so i feel this is a lack problem on the heroes flexibility.....i hope to fix the problem on the next version. when i am fighting the boss as know as the ''skeloton king'' the problem just bothering me when fighting bosses.i hv no time to evade the bosses when i am trying to cast the skill
