I play with others all the time. But they don't have to help with menial or easy tasks. Who'da thunk? Just because a game is multiplayer doesn't mean you have to do everything with everyone. Otherwise even duoing crap doesn't really fit the definition does it? Do we do everything in 18 man alliances? Well maybe you do.
That's a silly argument that silly people inevitably bring up whenever they hear an inkling of silly soloing in their silly "MMO".
