Two things to add:

- All classes in this game are viable in raid, however managing optimal setup is something that could be worth learning if you are interested in it (for example, BRD and DRG are great together). If being optimal doesn't matter to you then I would suggest not getting sucked into the viability debate and play whatever job you want in raid. Also, stormblood is in 3 months and things will change drastically anyway, so don't get attached to the way your class plays right now.

- If you want to see how BRD works at endgame, do Palace of the dead in quarrymill.
