Ive ran almost all the experts on my rogue tank at lvl 50 and i would say most of the teir 1s you can farm boxing wont be able to alot fo the t2 till maybe you get some t2 gear from farming plaques from t1s. unles your good at movment i know alot of t2s are aoe debuff pull ins dead type stuff like RD first boss for 1. but if there is a will there is a way. if u get gear i think its doable but hard. Im up for the challenge on my boxing team once they get there. atm they are almost lvl 30.
So far every fights been good. IT was a joke DsM was hard on last boss till i figured something out. Dsm last boss if i use all ranged 4 out of 5 times he throws the crystall at a ranged person some time i never have to move the tank. so i position the ranged then pull with tank get tank in spot and just control a dps. then i just switch screens to who ever gets the red crystall and move them. and keep spaming keys as i move. its worked very well i went from 24 to 28 in one day farming dsm and now i have nice gear and its even easier.
