i would love a multyplayer in the aftergame battlefields. you have doen all your SP quests that most of you say you like, and then you can choose to face oponnents in the MP battlefield or not. i think this would have been a great solution.
very curious about DD2's MP. waiting impatiently
I have to agree with others that development time will probably outweigh the profit, but as I can see, Battlefields or co-operative Hero/Death Knight would be the only multiplayer options here. The other problem is the abundance of non-combat skills. These can severely disadvantage some characters in PvP.
I feel that RPGs (more than just combat based) are often the wrong area for PvP. If you want combat, play a combat game, but PvP story driven games don't work in my head.
