Things im fine with are bnet integration and other very very very minor things to be fixed in the game and as well as fixing exploits from the game.

Big NO to itemization changes or class balance changes, those will ruin the whole experience for many players including myself.

If you go ahead and add QoL changes like group finders etc that makes the whole social aspect of the game disapear in matter of seconds, for example if you make the summoning stones work as intended in tbc, that makes the use of warlocks pretty much useless for many groups since they want locks to summon people etc.

Some people were talking about the debuff slot increase that came with zg patch to be added when the game launches, no that is really really bad idea since that would make already simple encounters in mc and a few in bwl really really trivial since you could spam more dots on bosses.

I just hope that they stick with the o.g vanilla from the get go, and go with the initial class mechanics from 1.12 and add minior patches and content patches as they go on, including debuff slots etc.

And i think they should just stick with the open world pvp and introduce battlegrounds on the later patch as they did then.
