Reading the forums i have gathered the following feelings about jobs, note i don't have one character yet that is level 60 so i have not touched end user content

PLD- doesn't get enough DPS so can't survive in alexander savage
NIN- Lags on certain mundra, so broke
BRD- broke


So should i even bother leveling up these jobs since they appear to be gimp in end game content. Or do they do fine in those raids and just a few people are having problems?

If i should avoid these classes are their any other classes i should avoid that don't perform will in end game?
