Looking at it realistically, TLT is going to be our last expansion about big cosmic themes for a while. They're signing off (this time for real) on the end of the wow story as we know it. Answering a lot of questions (supposedly and hopefully) before we're all too old to play the game ourselves. To quote their announcement anyway.
The saga/expansion/whatever after is not going to be anyway here's cosmic saga about interchangeable coloured goop number 2. Its going to be labelled as a new start. Whether that's likely to be a revamp or somewhere entirely new or a time skip, is anyone's guess.
From listening to recent announcements and videos they've released. They've made it clear they're happy to support wow going forward. A lot of people have claimed its going to die for many years, and at this point I fully believe that's not going to be the case. (At least until they fuck up drastically) and they're going big on pointing out how climatic the end of this saga will be. They're bringing all of the big guns out of the box this time.
They understand they have an aging player base, they are trying youtube shorts and tiktok advertising to bring in new blood. I have seen a lot of new players come in and done my best to help them get involved with the game, but sometimes the sheer mass of content they've missed out on is too much for them to catch up with. This gets ignored a lot. WoW is very, very unfriendly to new players, especially the younger generation that may have never touched an mmo before. With honesty, as much as I personally love its jankiness at times, it can be very off-putting if you're not used to it.
The new expansions is going to be at the very least the beginnings of a new big Era of Warcraft. They will want to bring as many new people into it as they are currently ending a lot of the big questions regarding the game we've had for twenty years. It will be branded as such.
I do think the class survey was real (maybe im stoopid) But I would not be surprised if a bunch of new classes being added in at the start of a new saga. We're going to get a squish soon anyway. I also am expecting a big revamp on character creation.
In my opinion, there's going to be a new large continent. Kalimdor and Eastern Kingdom size. Almost certainly Avaloren. Where we have a large level up path to reach endgame.
I really don't see just another expac being announced next. At the least a saga. Its not enough at this point to go here's Fel/Death/light/Order/life/Void saga. It has to be something to build onto something for those new players, and for us oldies as well, who do deserve well thought out, well built up, coherent storylines after 2 decades of subsciption and expansion fees.
Why does new player who is 18-25 and plays wow as their first mmo in 2029/2030 care about Void, or Fel or any other cosmic force?
I do personally see an expansion where we leave for Avaloren as a smallish expeditionary group with limited, possibly young hero characters. - The Duraks and Talia's of wow possibly - are rejected by the Emperor, imprisoned as a slaves. Break our way out, and slowly intergrate into the new world. My favourite little theory is the emperor is in control of the storms that protect Avaloren, lowers them to allow us and Faerin in, only to execute her for being of secret royal blood which could be a threat to the legitamacy of his rule, only to re-apply the storms leaving us stranded, with no way home. (Damn teleport lore ruining this but anyway)
Have 3 large continents for 3 expansions. Set the Arathi emperor as villain of the saga. Have us escape from the capital, steal ships, and land at the first continent. This first continent can be made freely, it can have entirely new cultures, civilization, races, everything. We have to build our way up to make allies/help the locals/bolster our ranks to take on the empire itself in the 3rd expac.
This would leave all of the zones we've been to over the years free of us for a saga or possibly more. Make that saga last in lore at least 10 years. Then we can have the revamp when we eventually return. We can see how leaders have aged, how alliances have broken or evolved how the lands have shaped. Who's taken over now?
I'm not suggesting Wow 2 by any means. I'm sure even blizzard know by now that's suicide. But I do expect a large portion of the branding of what's to come as a fresh start in terms of story. Jump in now for the new Era of Warcraft. Be there for the beginning of the next 20 years. Don't be 2/5/10/17 years late again.
(Disclaimer: I am not suggesting a wipe of any bodies characters/collections/achievements by any means - Never do this)
