I'm giving a shoutout to PVE-OfficialServer33 as well. The thing is, the reason I HAVEN'T been on this server much recently is that,,,*wait for it*,,,I've been busy rebuilding my SE base from the last migration. Feature not a bug?
If WC is going to offer multiple DLC server types, I'm not sure each server activity alone reflects overall player participation. My main base is the Island. There should be some accounting for my being on SE , Ragnarock and Abberation servers. You can't be everywhere at once, and WC is offering DLC's that by definition mean your time on any particular server is going to be diluted.
