this has many views but no replies, but i think your idea is very cool to say the least,

4 manning 5 mans, but in my experience doing end game 5 mans, it takes a bit of coordination, with 5 people, everyone has to do the part when its called for, your idea sounds awesome, partnering with your brother 2 characters each, i try shaman

everyone likes to multibox shaman, and for some reason it works, your plan about 2 shaman 2 paladin sounds plausible im assuming you mean ele shaman for dps or dps in general and 1 paladin tank while one heals, and all offhealing coming from shaman

this sounds pretty cool in concept and it seems some difficulty could be worked out if you played the same class by this i mean you play both shaman and brother plays both paladins, (actually paladins could be more difficult to multibox if theyre playing different roles), but i would also look into playing another account or just finding a friend or someone to play the part of the fifth person :thumbsup: good luck
