Look. Every expansion we’ve dealt with the same garbage.
Alliance vs horde. They’re fighting.
Look, a big baddie that threatens both factions.
Let’s unite against this threat.
Threat defeated. Now we’re at peace.
Oh. apparently someone sneezed at another guy’s face. Back to war.
In order for an interesting change to happen with the world of warcraft, sometimes even the most fundamental things must change.
I’d even go as far as considering raiding and mythic+ for both factions should become a thing. That way, alliance will also not have a disadvantage when it comes to high end raiding, because now they can do stuff with horde as well.
World pvp, can turn into a world dueling, where you won’t die by the hands of your enemies and just lose. But losing gives you a debuff that reduces your stats or something to make it equal to dying in terms of negative effects. That way, we get to have world pvp and it’ll make sense if both factions are now at peace.
Lots of ideas can be done with the system.
And to be honest, mixing the factions in some aspects is by far better than dividing them and then dealing with constant balance issues, and HORDE or ALLIANCE FAVORITISM complaints.
