I've read many posts about Sorcs TR'ing one, two, three, four, one hundred times to get the past life feats of wiz or sorcs so i started to wonder..is it really necessary to get those feats to become usefull in epic contents? Im almost a lvl 20 pure sorc with newbie equip and the idea of TRing and gettin again to lvl 20 doesnt really make me happy and joyfull..i was thinking more for a GR since ive messed something up with my build..what do you guys say about it? Is the TR a MUST?
