Not specifically no. Unless they’re games i’d already be playing (wouldn’t mind that at all if that’s the case)
I’d imagine that’d be something neat that they could tack onto classic-wow-seasons (like SoM). Cosmetics for retail wow as a reward but that do not affect gameplay at all.
No, thankfully blizzard cured my need to be a completionist in their games due to stuff like this, or the infinite credit card debt it would rack up trying to do so.
If I can’t have all of it in a game, I don’t care to have any of it. Game doesn’t have the same magic it once did for me to care about that stuff anymore, on top of every passing season in WoW feeling more and more dead, quicker and quicker.
The ONLY game I’ll ever try to collect everything in, is one that comes out with no cash shop that forces me to buy it all to complete my collection. So realistically, I don’t ever need to worry about that
