I just felt compelled to add my 2 cents here, as I am currently (as I put it) PL'ing a healer (contr). HOWEVER...tactics I've used (NOTE: I have 2 top of the line pc's side by side and 2 accts, so I'm able to do this solo):
1. Teamed lvl 9 with lvl 32, SK'd. XP sucked (same as I would get at normal lvl 9, as my 32 blaster isn't a great AOE'r....YET (AR) =).
2. So, I had a fire blaster that I wanted to lvl. Blaster was 18, controller was still lvl 9 (gee...PL?). Had to SK again, but got lil more xp, as kills were faster. NOTE: In every instance my controller was active healing, stunning, etc.
3. FINALLY....had lvl 13 blaster (forgot bout her hehe)..fire again. So, I've been teaming the two of them for a WEEK (since last Sunday). Currently, the blaster is lvl 16, and the controller is 15.
That considered power lvl'ing....I think not. Nor did i EVER abuse the rules of conduct.
Cheers to those standing up for this.
Prissy =)
