you are wrong. massive multiplayer online.massive = huge, large, big; multi = alot, bunch, several; player=person,people,human,bot. nowhere in there is there a must group up, party up, etc. you and alot of other people just thinks it does. also, just because alot of other people believe it. does not make it true.MMO means "Massive MULTIPLAYER Online".
Sure it means group and party play / PvP. If someone wants to play everything solo, the a MMORPG is definately the wrong game.
If the devs design everything to be made solo, then the devs haven´t understand the title "MMO".
