Time to do something about summoners lagging the hell out of the game? Please, Gaz.

There was a time I enjoyed patrols. Wherever, whenever, that was fun.
Actually, one doom is enough to make boss fights completely unimmersive, trivial and utter crap. All I can do is stick to the fight, watch the slow-motion lego movie, and loot. Not fun.
Frankly, I don't know how to fix this, I'm not a software enginner. But I think something could be done before this thing get completely out of hand.
