ig in a way for your 6-9 summons to work you'd need 3 egi buttons that randomly shuffle after a demi like an auto astral draw? otherwise i can see the hotbar being totally bloated.
this actually reads like you want SMN to be BLU oddly.
sadly the hard two minutes isnt going to go away / it'll perhaps be replaced by x minutes bursts and cooldowns increased on major buttons for it if they do make wholesale changes in 8.0 which i aint counting on.
i dont think we have the right answers to what 'fixes' summoner. but at least we're sharing ideas.
