As a die-hard Horde PvE player, Elysium's 10/10/17 announcement that all servers will probably be merged into 2 PvP servers before TBC's release was the deathknell of my personal participation as well as the demise of the best legacy WoW PvE server in existence. This is a sad, short-sighted decision.
There will always be players who will never play on a world PvP server. Removing this option will only create another loss to the playerbase, including mine. Elysium has provided an excellent vanilla WoW experience, but this lack of consideration for the PvE players shows a lack of foresight and respect for their patronage.
And so it appears that our only hope is Crestfall's PvP + PvE server structure. It's a shame that we have about another year to wait for their Benediction core, but there's no reason to continue advancing on Darrowshire when we already know that PvE players are probably going to be forced onto a PvP server.
Tip - When you're running a business, even if it's a non-profit business, never take away your patron's options. Some of those patrons will go elsewhere and take their donations with them.
