Hey guys¡ I know that we have a lot of Legion before even hearing about the next expansion, but its always fun to speculate, and I think that they might be some chances that another ''Cataclysm'' happens. Personally I'm loving Legion, and I would love to finally see a single timeline in WoW, and not the mess that we have right now, and I really really think that the next expansion is perfect for this to happen, and here is why:
1- Of course we have to talk about the new scale tech that they developed in Legion. I think that is amazing. They had already talk about how to implement it in other parts of the world. WoW is huge and it's a pity that after one expansion ends their zones are forever forgotten. They are already experimenting with it (Silithus miny holidays comes to mind, invasion event...), and it gives them the chance to implement scaled leveling.
Nowadays you do 10 quests in a certain zone and you can move to the next one without finishing the storyline or exploring the full zone, which I think it's one vital aspect of an MMO, doing that feels good and makes you feel more connected to Azeroth, instead of doing some quests and dungeons that aren't connected.
So if all the zones were like the Broken Isles ones, you wouldn't need to change zones constantly¡
2- Cataclysm Azeroth is already older than Vanilla Azeroth. In a MMO, I think that everybody would love to see the world in which we live evolve, that our actions have an impact; and next expansion is the perfect chance to do that (more about this in the next points).
3- They finally introduced in Legion the tutorial for new players (Broken Shore event), so I say that every new PJ should start in the Broken Isles. I know that is a crazy change, but that would allow them to make a single timeline, and leveling isn't that important these days, they give us a free max character with every expansion ¡
4- The lore moment is perfect ¡ They could combine the Legion invasion (which we know that it's having consecuences in all Azeroth, not just the Broken Isles) with Azshara / Old Gods invasion from the seas¡
We know that we will face Azshara / N'Zoth eventually, why they wouldn't attack us now? After invading Argus, we are weak, victory over the Legion isn't easy, and we still have to clean their remains on Azeroth, it's the perfect time for them to strike¡
These could lead to major new storylines in all continents ¡ Even in Outland, I would love to see whats happening there (although latest reports seems to establish that it's disappearing, but that's ok, less work for Blizzard). Not really sure about what to do with Draenor TBH, it's just to recent to change it.
So this would obviously be the main issue, revamping all continents at the same time would be a enormous task, I don't see them making it in one single expansion, so I thought that they might try a new approach, establishing in the map an ''Old Azeroth / Outland'' (the ones which we have today) and ''New Azeroth /Outland'', in which they can start revamping Kalimdor and the Eastern Kingdoms, and after a while Northend, Outland and the rest, maybe in patches?
FINAL PRODUCT: I think that it would be something like this:
100-110: new characters starts in the Broken Isles, scale tech still applyes, so when you are 110 you can move to the new zones.
110-120: revamped Kalimdor / Eastern Kingdoms (including Cata zones).
FINAL PRODUCT II: another chance would be something like:
1-110: revamped Kalimdor / Eastern Kingdoms (including Cata zones) and the Broken Isles. The Legion Invasion it's a single story, so this continents could be shared.
110-120: new continent.
FINAL PRODUCT III: I would love to see this one but I think that it's the most complicated because of how the timeline would feel:
1-60: revamped Kalimdor / Eastern Kingdoms (including Cata zones) and the Broken Isles (starting in your race zones, not in the Broken Isles).
60-110: revamped Outland / Northrend / Pandaria /Draenor? (with one continent you could reach the level for the new expansion, with new storylines in all of them, ideal for leveling alts¡).
110-120: new continent.
Now that we talk about levels, this are just numbers, I think that is hard for a new player to see that the max level is 110, so a revamped leveling system would be nice. As I say, our level is just a number, and while we are leveling, many levels doesn´t give us shit, not a talent, not a skill, and it's boring. So why don't put the max level in 60 or 70, and scale the zones according to that level? Just give it a thought.
Anyway I may edit this post later because I'm probably forgetting things, just let me know what do you think¡
