I’m hyped bout classic but one thing I’m sure of is bosses are just going to die so quickly as the current raider mindset is like at least 10 years above where it was during classic obviously....
The sheer number of consumables that players could use during vanilla but wasn’t really ‘standard’ until late late Naxx. The fact that I think nilhilium were the first guild to incorporate that all players in the raid were flasked.
The amount of extra power a raid will have during progression with all consumables on. With voice coms being standard and communication, understanding being so high that it’s possible to have current end bosses with such tight mechanics.
I raided in vanilla as a healer and the only thing that was required of me is that I had enough mana pots/ dbm/ decursive. And my healing officer at the time told me I needed to downrank my spell. Which I figured out with him by trial and error.
By the time classic comes out the sheer volume of guides how to spec/rotation etc which spells to use will completely trivialise content and the only thing people will be gated behind is the gear check.
Basically what I’m trying to say I think the bosses should be buffed ever so slightly that everything isn’t one shot.
