The game keeps track of what teams you are using in different parts of PVE now, so you can have a special team (well, three special teams actually) for each LoL without having to swap toons every day. Pretty nifty!
Tried out a new auto-team for Assassin LoL today. VHE, Nomad, Gunner Golden Son and Desert Marauder. Works like a charm! With perfect hit, attack buff and critical strike chance (from chance talismans), the GGS usually kills the whole wave in one hit while filling up the fury bar to let VHE go bananas on the boss.
