I’ve never seen a more dead arena expansion in my life, and it’s such a shame because Wotlk is so close to something really beautiful. At the same time, that beauty is decimated by a few specs (HPal, Preg, Ele, Arms). I think with a few minor tweaks, the next two seasons could be incredibly fun, and not front loaded by the exact same (incredibly droll) 3 compositions.
Holy Paladin: Sacred Cleansing is the obvious issue. Instead of having it provide a 30% Resist, consider changing it to a 30% Reduction in CC. This way it still provides some utility, but doesn’t just straight ruin the game.
Preg: Just destroy the spec. If it existed in this state back in the day, you would have gutted it. More so, it gets even more oppressing as they get better gear. Nip it now, and maybe change Art of War Procs so it scales off of weapon damage, so it is still useful for Ret, but does very little healing as Preg.
Ele: I’m not sure exactly what Ele needs. Maybe an ever-so-slight tweak to Astral Plane so instead of taking 30% reduced damage while stunned, they take 15-20% reduced damage. They just currently have no weaknesses, and need an minor tweak to survivability.
Arms: I’m also not entirely sure what Arms needs, but it’s absurd that Warrior/Hpal is allowed to just absolutely massacre the twos ladder for the entirety of the expansion. (Although, if I’m honest, the Arms oppression may be more due to Hpala’s being broken than them, so maybe the nerf to Hpal will be enough).
Anyway, those are my thoughts on some very minor changes that I don’t think would shake-up the Meta all that much, but would also allow some other classes and comp variation to shine.
