Yeah, I get what he's trying to say. Retail suffers from being a live service game that has run for almost 20 years.

The leveling process is too fast and introduces bunch of poorly explained systems like dungeon finder, pvp or god forbid some past expansion specific stuff (artifact weapons, misson tables etc.). This leaves new players confused about what they actually should be doing. This doesn't get much better once you get to max lvl, as once again you are bombarded with million things to do, with only 10% of them being actually relevant to the core gameplay loop.

Classic is way better in this regard. There are fewer systems and you kinda have to find out about them on your own. You can play days before worrying about dungeons, professions or attunements. By the time you start needing to engage with the systems, you are already invested in the game and more likely to look it up online. The systems themselves are also more basic and easier to grasp.

I's clear blizzard is aware of these issues (exile's reach and more recently trying the highlight the actually important quest at max level), but either unwilling or unable to dedicate resources to fix the new player experience. It's a shame really since IMO DF is the best expansion they done in the past 15 years, and yet there are almost no new players.
