Is this a spot-a-person-who-doesn't-really-raid thread?
Awful, awful ideas.

Crafted gear isn't superior to the top tome/raid gear available. The fact that it allows to progress faster however is a good thing. It allows players even if unintentionally to find unconventional ways to tackle content, overcome it through the use of mechanics outside of the actual battling. This makes the game feel whole. If you want all balance all the time might as well remove all the gear and preset all the stats. That's gonna be fun.

Scholars and White Mages are NOT gonna be on equal ground if you gimp the fairy through Cleric Stance because White Mages have Regen. Also Scholars tend to DPS more not only because of the fairy but because they have easier ways to restore MP and a super useful tool called Lustrate.
(Also no, it doesn't matter if you summon the fairy while in Cleric Stance, her stats aren't altered)

Two-tanking is already properly enforced in FCOB, very creatively, by multiple mechanics. There's no need for every enemy move to be a tankbuster.

Nobody likes to fight trash. Especially not when the raid goes on farm. The content is built around the idea of repeatability and pretending trash is anything but a minute obstacle is just gonna get on people's nerves. Trash right now is used to wake people up for the raid essentially and that's a pretty good use.
