I'd argue this is a major FFXIV problem, not just with Monk, although I haven't played BRD or MCH. Especially with tanks. Like on Warrior, you have 1-2-3 Butcher's Block, 1-4-5 Storm's Eye, 1-4-6 Storm's Path. There's very little variety and choice you can make. It's too simple. I could go on but I've already written a lengthy piece about tanks in general.
