i agree if your going for 5 box level all the characters together, it is fun you meet lots of people 90% of the time call you a bot but hey comes with boxing i guess, normally i give them a buff and blow them a kiss and leave them too it.

you will also get a pretty early heads up how your characters are going to 'feel' when your 70, just take them to an instance pvp what ever at when your about 19 i know all classes take a huge change later on but you will see what i mean, ive just (like tonight ) swapped from 4 locks and a priest to 4 priests and a shaman. I really wanted to change becuase i found no real challenge in the other set up with voidwalker tanking, theres very little purpose for a priest other than to ress when your talking to people and it causes one of the locks to die :s and at least the 4 priests 1 shaman is alittle more unique set up, dont know of anyone else doing it on here (there could be a reason for this ). Unlike the warlocks priest combo which is very popular.

anyway slower yes but i think it might save you any sence of regret or doubts about your class set ups.

quests are pretty dull doing things 5 times over but its not too bad. Imo level them as a team you get a better feeling for them, its a hell of a relief when you get that final item to go with the 49 others over your other toons to complete that quest

but play anyway your going to get the most fun out of even do 50;50 boost them in an instance till they are strong enough to handle it themselves as a group. I was getting so sick of rfk grinding, best advice is have in the corner of your screen youtube running, find somthing like never mind the buzzcocks (british tv before people say wtf?) and just watch shows on tv keeps you sain.
