This has been discussed so many times.
PvP gear is fine. If your not doing well in wz's its because your bad, not because of the gear.
My main is bis geared Sin, and I finaly finished lvl'ing a jugg to 50 today, and been doing wz's most of the day in recruit gear.
This was my best result.
Ofc. I am not on top every game, and I can feel a difference in gear, but I am far from useless in recruit gear with taunts, interceeds cc etc. and I can put out enough dmg to justify me beeing there,
TL;DR
less QQ more l2p
