Out of curiosity - why Herod with Bigglesworth? Both have healthy pops, and are not nearly as in need as other servers.
If you want to make the game truly healthy (with regard to PVP health as well)- here’s what you need:
Benediction + Herod + Rattlegore + Skeram = 13793A/13950H
Netherwind + Earthfury + Anathema + Stalagg + Kurinaxx + Smolderweb = 4556A/4435H
Thunderfury + Bigglesworth + Heartseeker +Arcanite Reaper + Felstrike + Incendius = 5161A/5476H
Bloodsail + Deviate Delight = 2028A/650H (Slightly problematic since it’s RP/PVE server - but there’s no PVP anyway on the other servers so it isn’t like they lost anything there)
Grobbulus + Kirtonos + Blaumeux = 7162A/6188H
Sulfuras + Kromcrush + Pagle = 8647A/8045H (Again two PVP servers into a PVE server but it doesn’t matter there’s no pvp anyway)
Fairbanks + Westfall = 4806A/4718H (PVP + PVE again no PVP anyway)
This smooths out there imbalances across PVP servers and adds some opposite faction flavor for two PVP servers.
Aside from this - you’d have to enable PVE ----> PVP transfers to allow for people to move if they choose to back to PVP and then FACTION LOCK THE LEAVING as they get lopsided so this garbage doesn’t happen again.
We all hated having names like: Brixtan - Deviate Delight, but it lets us keep our names when we move. The technology is already there, so it isn’t like a huge lift for Blizzard trying to recreate the wheel.
This isn’t hard.
