The real issue here is that the other “pvp” servers (as they are effectively all single-faction) are not true “pvp” servers. As the devs pointed out, they are de-facto pve servers.
So tell me, why any substantial group of people who have long been on de-facto pve servers would move to an actual pvp server? Short answers - generally speaking they wouldn’t.
If you’ve been living on a de-facto pve server, your natural inclination is going to be to not be incovenienced by pvp. Had you wanted pvp you’ve always had the option to go to an actual pvp spot but you’ve actively chosen not to.
Could a bunch of people who want to do wpvp but who have been generally unhappy for a long time due to being on a de-facto pve server move? It’s plausible, but unlikely. If they’re in a raiding guild they’re almost all going to follow their guild. And guilds, as pointed out, have 0 incentive to move to Grobb. So the only people who will be willing to move to Grobb are those who prioritize wpvp over raiding. Thus, the number of people who actively care to raid will not substantially increase.
New / returning players will overwhelmingly make the “smart” decision to go to the mega-servers (as devs have pointed out that’s what the community likes), so Grobb will die in time. This isn’t an irrational stance to take and devs need to keep this in mind.
Yes, allow people who care about wpvp to move to Grobb, absolutely. But also allow those of us who want to prioritize raiding over wpvp to escape what we believe is a sinking ship. That’s why you’re allowing everyone else free moves to a mega-server right? To allow those who are currently on sinking ships to escape. All we’re asking for is the same option.
