Oomkins are quite the fishing buddies, too
But srsly, play whatever, including moonkin.
Eventually there will be raid spots for everyone and make sure you let everyone know your build going into raids, or better yet tell them exactly what you need. As MT in past, I cant help but to stick up for someone focusing on their dream, no matter how meme-y. Plus we love shamans.
The fights last so quick right now compared to vanilla (and are easy compared to m+ imho) that I just dont see the big deal at all. I really wish other players would step out and realize how smooth it is to progress without having BiS and some theoritical speedrun meta parsed out over a million private server runs, but I digress.
Total generalization but you probably will have better luck on a pve server, as there seems to be a more accepting attitude of the non meta.
PvP servers right now are in super anxious mode with p2 and the upcoming push to goblin sap their way to marshall sets.
