Agree. Widow - Santa/Primarch - Widow is currently the most dominate configuration in the game
I have lost one battle in the last 100+ running Widow - Widow - Santa - Widow, and it was to someone running Widow4 - Big Rig - Widow3 because Big Rig Procd and then Both Widows procd and wiped me out b4 I had a chance to move
Anyone struggling in pvp should aspire to build a primarch and surround it with the fastest toons you can get your hands on (Widow, Harbinger, Crap AI, Rouge Ultra, Chieftain, Meta)
