Whenever a class has training wheels abilities/passives (e.g. Monk healing elixir in Legion, Paladin autotrinket/auto bubble in Legion, Warrior second wind in MoP) that require very little skill to use/any and are insanely rewarding for little to no cost, it throws off the meta.
My wishlist (specifically) for classes:
Warrior:
Shattering throw (confirmed) - A unique ability that makes us the 2nd only class able to remove immunities.
Charge stun baseline/talented - Vry self explanatory. Great disruption/initiation tool, more reliable than the root and sets it apart from other mobility abilities.
Stances (Reworked, but returned). - Make using stances part of your rotation/self explanatory, at least for arms which is supposed to be in the middle of fury & prot.
Weapons: I’m unsure if it’d be fair gearing wise if warriors have to have different weapons in their bags to play optimally, unless the bonuses would be significant. A better option would be to allow us to just stick to 1 weapon, but let us transmog different appearances on our weapons based on our stance.
A reliable self healing tool (e.g. enraged regeneration) for all specs alongside victory rush. - Quite self explanatory. It won’t make warrior immortal. It won’t take away from other classes fantasy, just as hunters exhiliration/rogues crimson vial (which was directly taken from warriors, btw) don’t. It however makes solo gameplay way more fun which outweighs all the negatives.
ARMS mastery: Bring back raw damage increase. Make arms a heavy hitting spec once more. When you get to execute range, execute actually does what it’s supposed to do. Overpower should feel overpowering, punishing classes like rogues/demon hunters, as it did for majority of the lifespan of WoW without breaking the game. Arms should be all about high sustained damage from constant pressure, with fury keeping its more spikier, burstier gameplay.
Give us a baseline stun. Throwdown, Stormbolt, shockwave/any other idea will do.
A few outliers that I know won’t hapen but I’d want anyway:
Make mortal wounds effect baseline for the whole class. Prot, fury, arms.
Bring back gladiator stance!
For other classes:
Priest: Bring back spectral guise/improve on it.
Bring back devouring plague & shadow orbs for shadow priests.
Hunter:
All abilities castable while moving. Mobility’s hunters trademark thing and should be where the class excels, regardless of the spec.
Turn beastmastery into the pet spec like it should be (see Rexxar).
Turn survival back to what it was pre-legion: A dot kiting survival spec.
Bring back specific pet family abilities.
DK: Presences.
