I think people like buffs. The can of worms this opens, however, is that paladins and rets werent even in that bad of a spot… Holy and Prot are S+ tier and Ret brought a ton of utility. Like, A METRIC TON of utility. They are also quite bursty. Theyre just built with gaps into the rotation so their DPS doesnt really ramp up until later parts of the game when tier sets can cause resets that fill those gaps. This is part of the reason their damage feels so strong in PVP - they unload on you when theyre in range.
By contrast, Warriors are in a worst position. The fact rets get buffed but warriors remain in the dumpster fire is why people are scratching their heads. It opens the question “why rets, when there are others that are worse off.”
Prot war is viewed as the worst of the 4 tanking class spec combos. Arms is total trash, requiring high uptime and little movement to spam slam to be in dead last place on damage. Their PVP situation isnt much better, slam is unusable, they are underrepresented in every bracket (below 10%) for obvious reasons - squishy, low damage, and low utility with unrelenting assault being the only silver lining that most can just ignore. Dead last or 0 representation in PVP tournaments. Yes, Rank 1 players carried by Rank 1 holy paladins can make some representation but as a whole, WotLK is rogue (25 rogues in top 100, 6 warriors in 2s for example, and in 3s, 7 warriors and 30 shamans…) and caster cleave dominated.
Then fury spec is the only “viable” spec warrior has and it was tied with ret in damage… but it brings relatively 0 utility. Commanding shout over imp is something your token fury warrior can bring but, no salv, HoP, bubble, offhealing, cleanse, sac, numerous blessings, judgments, replenishment, haste, crit, etc. If you have a feral you dont need rampage. The idea fury scales insane is also pure copium. We have the sims. It isnt until full ilvl 277 heroic ICC gear + shadowmourne that fury warrior is even in the top 4 dps. In full Ulduar Bis, theyre still 2k behind every other class.
Blizzard should have never touched ret because now a huge can of worms is open. I guess they kind of opened it when they buffed demo locks and improved their QoL with their spell power buff, but there is the very real elephant in the room that warriors are a lot worse off than paladins overall and the idea that they “catch up” is already being disproven by the current power curves and sims.
