It wasn't today, but I've been tinkering with playing a full support warlock. I use lumina and a sniper or gl and have a buddy using a bow and sniper or gl. Empower melee, empowering rift, well, lumina buff, heal nades. One shot hilarity ensues. I even landed a hail mary grenade shot in well for a kill on somone i couldnt see. Made for a nice clip :p
