this is what scares me the most (and what i know will happen eventually). when everyone has been playing for a while (few months?), they will have several classes unlocked and tiered up. now, when you get together with your friends, instead of being identified as an awesome wizard, or warrior, or enchanter, or whatever it's just: player1: "hey, i played wizard last time, this time i want to be the warrior." player2: "nah, cause i played warrior last time and we did fine so i'll stay as the warrior and you can be the wizard again or the rogue or the cleric." player3: "he can't be the cleric, cause my friend that's coming with us wants to be the cleric, and i'm going to play the rogue tonight." player1: "fine, i'll play the wizard but if that sword drops i still get to roll on it because my warrior is still my main." player2: "no fucking way! i'm the warrior. you can't roll on tank loot." player3: "well, my friend that's coming also plays a warrior so he wants to roll on any tank loot too, and i've been working on my shadow knight so i need to be able to roll on that loot as well, as well as any rogue loot, or druid loot, since i have one of those too. oh, and any monk loot as well."
