Question about GCD

[Sylkis]

For tanks, at higher levels it is only about mitigation/provoke timing (Off-GCD skills) and positioning.

Crowd control/debuffs are rarely useful right now, so your pacification/stun/silence abilities aren't used for those purposes.
MP is also not an issue for paladins currently, with only flash and stoneskin that use it ... neither of them need to be used often enough that your MP runs out, which makes the paladin branching combo (Riot blade) useless.

While paladins have a lot of tools, they are all rarely used so it reduces the job down to a 1-2-3 with mitigation skills. I blame the rest of the game for that instead of the job itself.
