If Team 4 wants to concede, I'm okay with resigning to Team 3 (Bullock/BBZ).
My hastily thrown together communion was overrun by Morrigans since apparently for some bugged reason the magic spell Solar Rays cast by Herald Lances weren't popping their mistform - waste of ~60 Astral Gems.
Judging by the few remaining lands of Caelum's on the map I would say T3's victory is inevitable at this point.
