So I think we should have a discussion about wow...
Specifically about a statement I read on youtube which actually made me realise what is wrong with both classic and with modern wow..
"Retail wow is all about the Destination, Classic wow is all about the journey."
If you really think about this... It's right. In Classic wow levelling is the main part of the game, once you hit max level, you get pre-raid bis, then log in once or twice a week to raid... And that's it there's nothing else to do.
Most of the time players spend in Classic is either levelling or PVP and it's because most of classic has no end game other than raiding.
Retail on the other hand has basically no coherent levelling experience, specifically for new players. You finish exiles reach, forcefully go to BFA content and start being called the hero of azeroth... Then half way through one zone of quests you get to 60 and get told that a new threats emerged and you should now be going to the dragon isles....
This creates a feeling where the journey means nothing and it's just about getting to end game as fast as possible to farm raids, M+, world quests, and soon delves.
Retail at end game though has a TON of content, there's lots of story, world events, loot.. more...
So overall... what exactly can be done about the feeling...
The least popular options would be to purge old content and make levelling take longer.
However I think I have a better solution..
Brand new players who have never touched wow before (so brand new accounts) will follow a linear story quest line that that will take them through a set of quests that leads up to a final encounter, at the end of which.. they will face down with a raid boss with a fully AI controlled 10 man raid group. And they will go through each expansion from the years and do the same end of expansion encounters that we have all done before.
So you'd fight Cthun (or KT) -> Kil'jaeden -> Arthus -> Deathwing -> Garrosh -> (skip WoD) Gul'Dan to get the illidan story -> Sargeras -> N'Zoth -> and then The Jailer.
Experiencing an abridged story for each before you kill them. It would take quite a bit longer than normal levelling but players can choose not to do this and just speak to chromie or something to get back.
Personally I think they should just remove content but that's a personal thing and I think too many people would get angry at that for some reason.
Also I want to point out that I don't think players should have that much power when it comes to levelling a new character.. Either level it or buy a boost.. I would rather wows story made sense, was told well and was engaging rather than giving players the power to turbo level characters. If you don't want to level in an RPG... imo find another game.
