Game is absolutely jam-packed with inconsequential, barely-differentiated fluff skills. I simply cannot give a crap about the fine-grained distinctions between Dragoon Spear Thrust #4 and Dragoon Spear Thrust #5.
Or Red Mage Gauge Builder (Light Version) and Red Mage Gauge Builder (Dark Version).
What's that? You have small hands and would prefer a smaller number of core rotation skills so you can get them all under your hand along with the WASD?
What's that? You wanted to reserve hotbar slots for some macros so you can shot-call for a pick-up group without using voice comms?
You're not getting that, keep these 20 glorified auto-attacks on cooldown instead.
