They wouldn’t - but if the add-on became prevalent it would almost certainly have a public facing database like the Armory started with. Then people will want to see it before they let you do runs etc. It’s exactly how WOTLK began going down that path.
And THAT is the reason I don’t think they would allow the add-on.
Actually, it was never the rewards that irked me about the Achievement system. When they added it, I remember dungeon mentality shifting. I would enter as tank or healer and have members of the group insisting on doing specific things to get an Achievement, sometimes bailing on the group if the Achievement was failed even if a boss was downed.
Additionally, it encourages a certain mindset I prefer not to be around - the “look at my achievement” and “we’re not taking you along unless you have this achievement”. Some like it, and Retail is full of it. I’ll be glad to get away from it finally.
The most explanation you’re likely to get is what they said at the BlizzCon panel. (Check out around 34:30 in the video linked here: ***EVERYTHING We Definitively Know about Classic***)
(1) They weren’t added until WotLK, so even if the code is there, the data isn’t.
(2) While it seemed innocuous, it layered on motivations - and vanilla Azeroth is a world that didn’t need those extra motivations.
Woah wooooh WOAH, hold up there. Elitist check’s have been around way before WotLK. Checking gear on Org bank roof was a thing in vanilla. It will be a thing in Classic and will always be a thing.
As far as addons, we don’t know about the armory. If there is armory profiles there will be addons.
I’m not talking about 2 different things - I’m literally talking about the same thing. If you have a d database tracking achievements for people, it is a PALTRY task to then summarize it on a public facing database.
Hope you see how gear checking and achievement checking are one in the same.
Person A sets a bar and expects Player B to meet that bar.
Using the defense of not wanting achievements to be used as a tool for elitism while ignoring all the methods that are still available? No logical.
As far as the armory, just because it was not around in vanilla does not mean there will be none in Classic. The armory is not in game. It does not change the game. Emphasis on the game.
It wasn’t around in during vanilla is an exhausted stance when it’s out side of the game.
Asking someone to link the achievement of downing Ragnaros (because that’s what you want to require them to have in order to join) is NOT equivalent to making sure the person has the appropriate gear TO down Rag.
