It's good to see that you are starting to enjoy yourself more as you progress, Gramlite. The low levels might feel a bit slow at first, but you will eventually get more off globals and more stuff. I have already posted the GCD rotations earlier for both AoE and Single target.

As for the WoW Paladin, the balancing there is a bit different compared to FF14. I never did play WoW Classic during the time, but I do hear that the Warrior was the tank period. Paladin and Druid were mostly for off tanking or off role stuff. They supplemented buffs to the other main roles like blessings and innervate for mana regen. As for retail version, we have to grind a cloak, a necklace and essences to slot in the necklace. We have to get the Strength of the Warden essence to be allowed to AoE taunt >.> Icy Veins suggests we PvP and get the reputation vendors up from the later 2 patches for some of the best ones.

The Paladin tank in WoW is something like this.

Pull with Avenger Shield and / or Judgement
Drop Consecrate ground AoE

Then it runs into a priority system of which one hits the hardest or grants the best survival. I will just list the base spells since the Azerite Necklace Essences and talent system can alter it sometimes.

Judgment
Avenger Shield
Consecrate (if you need to move it or it fades)
Hammer of the Righteous
Consecrate

The rotation here is almost the same for both single target and AoE.
Shield of the Righteous is an off global and hits everything in front of them. It additionally reduces damage they take for a few seconds.
They also have Light of the Protector to heal themselves or another ally. Last I recall, it uses the GCD.
Judgment casts reduce the cooldown of Shield of the Righteous. Critical hits reduce the cooldown timer more.

What you said was kind of right, Maeka. The Cataclysm expansion used to use Holy Power for the Paladin tanks. Only the DPS Paladins use it now. The Healer and Tank just use a cooldown timer with ways to reset it or reduce it now. You are right the WoW Players complain about how boring Druid is for tanking. They basically have Mangle, Thrash, Moonfire, then Maul or Swipe as a filler. Again, it is the same for both AoE and Single Target.

Hopefully this will feel relevant enough to simply make a comparison.
