I use to play a lot back in the day, I’ve not been around for much high end cotent in a long time due to life in general, but I’ve been around for a number of prepatches.
Balance usually goes out the window. Sometimes it’s because some classes get a move that’s overturned for later content, sometimes it’s because you don’t yet have a move you need yet.
The most hilarious and offending example I can remember was the wotlk prepatch giving paladins divine storm, which at the time was unresistable holy damage aoe on command and a short cool down of 6sec iirc that hit at full force even if they used a bubble to go completely damage immune. A ret player in AH blues and greens could tear through someone in late tier pvp gear for a little while. Elemental struggled some with lava burst being a fairly late in leveling but the xpac wasn’t bad for it since thunderstorms introduction made the spec fun.
So it’s possible things are out of tune (so many potions and foods healing for 0 being a sign of this mess) and can be fixed. Ngl I’m a little worried given the classes I tank on still feel amazing and powerful, my fire mage is less interesting now but still disintegrates mobs sadly faster than my more geared shaman, warlock feels similar, warrior I hardly noticed a difference, frost mage still shreds mob packs, but elemental feels squishy.
I will say healing in general feels awful, like trying to put out a house fire with a sprinkler. Resto is eh but manageable, holy priest still works but it’s damage is gone, like go wand something days again, and any hybrid dependent on tossing an off heal or self heal just does nothing but waste a GCD. Evoker healing looked like a struggle to me before, now it looks like a furious button mash to pray for procs and do even worse.
That is to say enough specs are bad or at least feel bad that I think we’ll hopefully see some good patches or the game may have few healers left as an entire role in the game seem pretty rough at the moment. I can’t image the game going back to the to the choices being warrior, rogue, mage, priest, or reroll these days like it once was.
For the first time I may reconsider my choice of tank, range, and healer I level this go around but take it with a grain of salt I’m fairly casual these days and by no means an expert anymore, just a fossil that remembers some old times.
