Were the classes the biggest mistake in BfA?

I think BM is in the best spot it's ever been design wise. Same with Havoc DH (although that's not saying much as it's a new spec). I find MM to be an atrocious mess that has the weirdest flowing rotation I've ever played. SV is great but it's melee and them changing a ranged spec to melee was the worst decision they ever made.

I don't think it had to be a bad decision, and if it had been made many expansions ago it'd have been fine. However, every new class introduced has been melee, so adding a melee spec in place of a ranged one was not a good choice.

Feel 100% the same.
It never felt like a good replacement for the weapons in Legion.

It goes deeper, they could have made the traits socketed items crafted by the professions and had each ring with one empty socket so that there was always choice or you could buy/craft the ones you wanted. That alone would have fixed many things with azerite gear in general.

Hard to pick what the worst mistake of BfA is when there's so many of them.
