It sent a REALLY bad signal to the community. This kind of thing breeds entitlement. It LITERALLY undercuts an insane portion of what the game was designed for, anyone arguing for the boost just purely does not understand game design and player psychology whatsoever.
The problem is that it’s a great source of short term cash infusion for good looking quarterly shareholder reports… so even if there were any talent left at Blizzard aware of these facts, it doesn’t matter, they would be helpless and told to shut up and sell the boost to players at Blizzconline.
We know it fed heavily into making bots far more profitable, which affected the economy, that’s old news… but Blizzard can conceivably deal with bots WHILE taking their boost money (not that they did a great job early on of this). The main issue is how it affects leveling, community building, and the new player experience.
Classic has been sold primarily as a nostalgia product. The ONLY marketing they’ve done has appealed to nostalgia. They have done precisely zero marketing on the games own merits, designed for new players.
If you’re a newer generation gamer looking to play the best MMO in the world (it’s still WoW classic, sorry weebs - your game is big due to an extrinsic cultural phenomena + Blizzard’s mismanagement) and you start the game fresh, the world is going to be severely more empty when the established community of now adults is constantly boosting new alt accounts to min/max.
There’s a lot more that feeds into this unfriendliness to new players than the boost, a lot of that is on the community managers not setting up good hooks and tutorials, the in-game learning systems are basically still OK in 2022 if they had supplemented them… but the active on the fly help from being mixed into an active leveling community was ripped right out. I just explained the entire PvP season transition to a new player in-game the other day and that guy was highly thankful but had zero clue, no thanks to these shortcomings.
If you remember WoW circa 2007 it was a way more diverse community, old man guilds (50s +), school aged kids everywhere (all of us), people in their 20s and 30s. Now it’s literally ALL 30 year old dudes give or take 5 years. I even played with a ton of people from all different countries on my US central servers, and it’s not like there weren’t global servers back then… but now there’s almost none of that. The sample size, appeal, advertising etc. was way bigger. Where the hell are our modern Mr. T commercials?? The nostalgia trip ad was cool or whatever but it’s not going to make ANY sense to a new player who doesn’t even know what an MMO is but COULD be sold on joining one.
You can argue that part of why the population is smaller is because MMOs in general make up a smaller portion of the gaming space now, with so many options available… but if you sell it right, people are still going to be attracted to the most quality gameplay (however that also has to include a slightly more active treatment of the live service from the devs, despite some good changes, there’s a lot missing).
As others have stated the boost also greatly exacerbates faction balance by providing an option that goes against the o.g. dev philosophy in terms of forcing people to get over it and just band together with their existing faction choice via the friction. Which does make a stronger community, that in large part laid the ground for the nostalgia of your original main character in the first place, assuming it was on a faction that you would have at one point been convinced you needed to swap off of but didn’t want to bother re-leveling. Your entire history with the game could’ve gone a different way and the experience could have been a lot more broken up had they offered this in TBC. It’s part of the reason WOTLK was the beginning of the end of the server community feel.
At the end of the day, the boost tells players that core elements of the game are worth skipping, and expects players to log in and setup a level 58 character. This is fine for 30 year old whales with some spare cash to feed their WoW hobby, but it’s terrible for the long-term health of the game when it comes to building a sustainable community.
P.S. the mage boosting argument SHOULD be moot, that should’ve been nerfed early on to be in-line with normal leveling rates while requiring the boostees to participate in combat to prevent AFK leveling. Really a no-brainer.
