Big disagree. You should always expect people to do what is in their own self interest, even if it’s at the detriment to a larger community. This is why we have laws. As an analogue, Blizzard are wow’s government, they set the laws, and in this case, they did not set appropriate laws to protect the players from themselves.
Lets have a walk down memory lane, shall we? The first wave of transfers to Grob happened back in phase 2/3 of OG classic. This was when layers were initially removed from the game and the big streamer servers had massive queues. Grobbulus was one of the designated overflow servers for players, so sure, while Blizzard didn’t FORCE anyone to transfer, the were highly encouraged to. This was Blizzard’s first mistake, encouraging players to transfer from a non-rp realm to an rp realm. Sudden transfers like that do not integrate well with a new communit, and led to a lot of clashing of players with different ideals. These free transfers carried on throughout the entirety of classic, with another fairly big wave hitting grob during ZG specifically (probably because ZG was a big catch up raid so a lot of people came back for it), I remember massive queues for the first couple of days for some reason, but they carried on all the way to TBC release.
Now, lets move on to Blizzard’s second mistake: Ignoring the worldbuff meta and leaving free transfers open on the current megaservers. Those free transfers are almost entirely why the pvp megaservers went 100-0 in terms of faction balance. With the worldbuff meta in full swing, and people not wanting to have to deal with getting ganked, people jumped ship from one big server onto another, creating the standard 100-0 pvp realm.
Grobbulus remained largely unaffected by this, as an rp-pvp server, there were enough people tied to the server itself for reasons other than raiding metas that even when population imbalances began to look inevitable (we were 65/35 at one point) enough horde actually stuck around. This is, however, where blizzard’s second mistake occured. As Grobbulus’ population continued to grow, they STILL kept it open as a free server destination, despite it already being a reasonably large server, and when TBC finally launched, we were hit with enough transfers as grob was now officially the only balanced pvp server left in the entirety of wow, and now, with the removal of the worldbuff meta, the people who actually wanted to world pvp, or were generally okay with it, flocked to the server in droves, and bam, a new megaserver was born. From this point onward, Grobbulus was now the permanent layer server it remains unti this day, and with the server closures, and grobbulus being a destination realm for THOSE as well, the problem was just exacerbated by the time wrath launched.
So you can see, by having free transfers available to grobbulus for so long, and at such key points in time, blizzard have been encouraging non rp players onto an rp server for close to three years now. If you don’t think that’s on Blizzard for mismanagement… Then I don’t know what to say.
