For my 9th life I'm considering going arti/rogue (18/2) and use the +20 for TRing for a PL that might otherwise be annoying. I'm not sure which would be the most annoying...I have 3 ranger & arti, a cleric PL and will have a rogue PL done next. (Not on a group TR train so usually going it alone/pugging with an occasional guild or channel group.)
My guess is barb or fighter...the former I'm guessing is more annoying than the latter. Most of the gear I have that's decent is repeater-build-centric.
