Monk is my go-to melee if I'm not healing, and honestly it just feels outdated. It hasn't had any significant changes to it's rotation since ARR, and it keeps getting these rather gimmicky mechanics that a lot of people don't want to bother with.

Not to mention keeping their buffs up can be hell if you're not used to it. The amount of times you could easily lose GL in fights like Tsukuyomi, O7 and 8 savage. No one wants to deal with this when every other melee buffs are either static, or so easy to keep up it's not a big deal.
