Mags with uni rank 28k scoring roughly 225k to 250k for me in ABX. Keep the shield active and there is no way to miss the 100k so it’s a safe play (currently building Stryfe).
5 seconds INV for PvP ~ 200% proc for PvE. Very rare and worth hanging onto. Good synergy with ITGB as both are PvP stats.
IMO - all 3 you listed do too much dmg for a strict PvP build. Cable is def a PvE build. Jean does well vs EMaw (bound to get an OP uni someday). QS is a PvP monster and also holds his own on PvE. Would look at going with a dmg proc for all of them. Hope this helps.
