Yeah I do know that feeling all too well. Was difficult enough to choose SCH for the relic weapon cause halfway I thought: Crap, why didn't I pick up the Axe or the Daggers...
Although I narrowed down my Jobs to the Limsan ones (WAR/SCH/NIN) for each role, I find myself enjoying all the others too (except for Bard maybe cause I almost never play a bow class in rpgs)
