It's not our strength that let's us defeat enemies but our skill level... I mean yeah we beat Zurvan but if he hit you it was still a huge problem... the ability to dodge his attacks is what let us win.... and if we are supposed to be alone in these battles then we are apparently face tanking every boss and still able to heal ourselves and work complex mechanics.... this is the single biggest issue I have with the single WOL theory... nevermind we are asked to completely ignore the fact we can SEE and work with 3-7 other people during those fights...
