The current WoW situation is deeply rubbish, I have to say. My wife and I have a bunch of characters we've been leveling, but if they get more than like three-four levels out of whack, they just can't do the same content at all, and it seems completely stupid, because the tech is there.
Like, when TBC time-walking is turned on, my L71 Hunter can group with her L103 Priest just fine (unfortunately time-walking is way crap XP compared to random dungeons, but that's a trivial fix), but the moment it turns off? Nope. Can still do Horseman together, indeed, my L110 DH can do Horseman with L30 Warlock or whatever, but why is it we can only do this tiny bit of content?
It's really bad with new/returning players, too. For example, a friend of mine wanted to come back earlier this expansion, but all his characters were in the L80-ish range (having left in Cata), and all my alts were sub-60 (at that point) or over 100. Sure he could make one character 100 if he bought the expansion, but he actually wanted to see MoP and WoD a bit (understandably), and I literally couldn't play with him unless I leveled someone up to his level, and stuck with him, and even then if he decided he wanted to play another character? Welp... I'd then likely be unable to play with that.
It's just silly. So I really hope Blizzard have SOMETHING for us here. There are a multitude of different possible approaches.
Has anyone been looking for the trademark yet or have Blizzard found a way around that. I remember Mists of Pandaria being quite well known before Blizzcon. Nothing this year ?
Likely to see more of those, after they introduced them in artifact appearances in Legion.
As for another revamp of old content: the question is, why would they. It's an expenditure of development resources and effort that simply isn't necessary, especially with boosts. The older the game becomes, the smaller the potential audience for new players that want to level through "everything". 120 Levels sound pretty daunting to most players.
After Cata they pretty bluntly stated that that focus in development on leveling content was a mistake. I can see them making tweaks to the new player experience, or simply slapping rough scaling on all old content, that wouldn't require too much. But full-on revamps, with art assets and new stories etc? Nah, never again.
No amount of updating is going to get some sudden massive wave of new palyers that don't exist.
People don't care about MMOs anymore. Blizzard would be much better off bringing back older players with more content in 110-120 and at 120, than they would be neglecting the end game for the nearly non-existent new players. I don't see what is wrong with end game being vastly superior. That is where most of people's time is spent, so it should logically also be where most of Blizzard's time and resources go.
I'd rather not sacrifice potentially new and interesting places and quest lines and dungeons/mounts/characters so that I can kill trolls in northeastern STV instead of humans under Kurzen. Or Naga invading silverpine instead of Worgen invading Silverpine. Seems like really shallow content.
The problem with this statements revolves around the fact - or opinion - that the leveling experience sucks "donkey balls." The entire game was streamlined in Cata; there's no sense of exploration; the mobs are trivial, and you out-level everything before completing 1/3rd of a zone. Yes, leveling scaling will solve the last two issues, but only a revamp will solve the questing-on-rails and lack of exploration issue. The game is in need of a major overhaul!
