1) Ragefire chasm.

pain in the ass instance, its so long to walk between bosses. its quite easy however and doing quite well with not much wipes. if I was more careful I could get it done without wipes. average time is about an hour for 2 bosses, (I took a break from killing 2 came back later killed another 2).

after getting concecrate its way easier holding aggro on mobs.

2) 1x pally (tank) 1x lock 2x mages - all lev 20

I think maybe I shoulda replaced one of the mages with a shammy but I think it might get abit complicated, I haven't levelled or played a shaman before so I don't know how complicated it could get.
