I think most of the players out there don't care about the pro/cons of being a whm or a sch. They play their class because they enjoy it. I play SCH because I like fairies, not because it's supposedly "better" than White Mage. I'd have played WHM if my favorite weapon was a staff. I rolled a PLD because of Curtana, not because it was better or not than a warrior. People on forums are acting like they were all doing/clearing FCOB, and like there wasn't any other kind of players in this game, but when I saw the % of people clearing T13 ( 0 to 5% depending of the server?), I realized that forum's reality was faaaaar away from game's reality.
A vast majority of the population don't care if you're playing a WHM or a SCH ( or the incoming AST) as long as you're doing good with your class.
