Recently rolled an op and scoundrel, was going to use them both for healing and leveling primarily through wz and KDY with a bit of planet stuff hither and yorn.
I tried conc spec at low levels, sucked and died like a chump a bunch of times, possibly a l2p issue with the class and spec, tried leth, kind of enjoyed it though found the damage lacklustre with limited skills.
Is healing the only decent option for low level pvp levelling and not getting sick of playing the damn class after 4-5 wz
