1. Add more dps buttons such as Procs, extra Dot's or anything to keep track of, shouldn't be intense but healers should feel different even with slight dps differences. Even high damaging attacks that cost a lot of MP, using too much will burn your MP.
2. Lower healing output on all jobs, I don't mind tanks or dps having some small cooldowns that have healing tied to it, but they need to be weaker, Healers cooldowns are also way too strong healing wise. (Get rid of per enemy healing effects on BW)
3. Get rid of some bloat skills & useless ones.

Just some things i can think of on the top of my head.
