EQ1 will be processing server merges beginning June 22. Twenty servers will be merged into ten. Only eight characters will be permitted on your account, so if you have characters on both servers that are merging you will need to delete some of them. The list of merged servers is here.
I was under the impression that EQ1 might actually be doing better than EQ2 since they had many more servers, but I guess that wasn't the case. As much as I'm sure they hate the impression merged servers leaves, it's definitely the right thing to do for the remaining players.
