You might not get the names you want on the server you're trying to be on unless you wait since many of them don't plan to announce anything so they can get their own names.
Asmongold has the largest following followed by soda. Alliance has Esfand, Staysafe, and a few more decent sized streamers. Horde has Venruki, Snutz, and the private server PvP people as well, but a few of them I believe are not rolling on the streamer server from what I've heard, including Venruki and Ziqo. So if you really want to kill streamers and their ilk your best bet might still be going Horde since I believe Asmongold, Esfand and Staysafe make up the majority of viewership concentrated onto one server together.
It looks like you're set on Alliance though, so do what you gotta do.
