... I literally explained why it's harder to play, are you trolling?
RoE has several really good applications in Rabanastre, Susano and Shin Ex as well as Deltascape, particularly O2(S) and O4(S); you do realize that we have a lot, like a whole lot, of unavoidable raid-wide damage in this game, right?
RoF does slow down the GCD, which is why you have to optimize OGCDs, making it slightly harder to use than BfB.
Brotherhood, as I already explained, needs you as a player to really know each fight so as to not waste uptime for anyone (usually the Monk, the Tanks & 2 other physical DPS) who benefits from it.

The rest of your post is once again completely off-topic. This thread isn't about the best and worst designed jobs, it's about challenge and demand; things you can't really comprehend, sorry. Obviously doing your rotation and hitting positionals is "brainless" when all you do is brainless content.
I'm honestly done talking to you, might as well try and talk against the wall.
