Eh, Blizzard has blown past authenticity and did a long time ago when they were stealth nerfing things then saying they changed it because it had to be changed for the health of the game. Like when they tweaked rogue pickpocketing rates to have a visibly higher rate of resistance against mobs, tried to argue it was purely anecdotal, then when confronted with a lot of angry rogue players early admitted they had tweaked pickpocketing resist rates and junkbox rates to dial back how much gold rogues were making.
The issue I can see is that the community is very divided on what changes they will and won’t accept, so Blizzard is going to gradually see what they can get away with. In a way I can kind of see it with like the chronoboon. There was no way Blizzard didn’t know the world buff meta was going to happen, private server players warned them about the dangers of keeping them and what kind of gameplay you would get. We were dealing with it in 2015 on Nostalrius, it wasn’t as prevalent before, you had a few people that brought world buffs but very few actual guilds required them to raid. Blizzard ignored adjusting that for the health of the game in a desperate bid to “keep true to the game” but then changed it with one thing and people rejoiced.
At that point Blizzard has found their in and are aware people’s preference to “No Changes” isn’t principled and is more “No changes that I don’t like.” So now Blizzard has a mandate to do a lot of things that some people will support, and won’t support but probably won’t end up quitting over. They’ve been given proof with the level boost and the tons of people defending it that when they do aggressively greedy things like this it won’t cripple the game. This is the present tip of the iceberg and you can argue “Slippery Slope” like the moron on the level 20 human rogue if you want but that’s what you’ll notice over the next few years with this project, Blizzard will get increasingly more aggressive with their changes and tell you it’s in the interest of game health. Like hell the level boost was even sold to us on that lie. “Well it’ll bring more people in, it’s just one boost and they want to enjoy TBC too, it’s for the good of the game!” That was also what they told us in MoP when they announced the level boost with WoD preorders, one per account and no more then within two months it became “Nah jk, we’re gonna sell these now without limit.” Or how they justified removing the cap on how many tokens one could buy with it being in the best interest of the game.
You watch, they’ll do something stupid, sub numbers will drop. They’ll blame it on people wanting to play TBC but not being able to justify spending money to play TBC personally and throw in the WoW token.
The fact they’re already forcing us to wait for tier 5 and Hyjal when it should be available on launch because “health of the game to not burn people out and make them not feel inadequate for being in t4 while everyone is farming tier 5” is a dangerous precedent they’re setting.
