If you want to have a discussion about why WoD pvp gearing should/should not be brought back then at least bring up a specific problem that WoD gearing had so that there something to talk about. Just saying “Many people dislike WoD among other things for how pvp was then” is vague and doesn’t even specify if “many people” disliked pvp because of gearing, or other reasons such as balance, gameplay, ect.
My reason in favor of WoD gearing is that gear differentials feel bad, and large power gaps are not good in competitive style games.
Another reason I can bring up is that honor gear in Shadowlands requires WAY too much honor to buy and upgrade to max rank. It is meant to be replaced by conquest gear, so having a massive grind attached to it does not make sense. A full set represents an over 200 random bgs grind. I outlined the honor cost difference between WoD and SLs honor gear in this thread a few months ago.
