My server is unplayable.

I have come to the conclusion that my server is practically unplayable. World PvP is too imbalanced at its current state, and being on a server that is a large majority horde, its very difficult to do anything. For instance, i am trying to turn in the timewalking badge at the Timeless Isles vendor, and there are 15+ Horde camping it, and not enough Alliance at a time to put up any kind of fight. I know there are 2 solutions, get in a party to instance to another server, or server transfer altogether. I personally don't think either are good solutions; for one, why should i have to make a group to instance to another server just to turn in a quest? And for 2, spending 200$+ dollars to transfer all my characters off the server is just ridiculous. I understand that I should have thought about it before i chose a server, and I did, but when i joined it was split almost 50/50 and now seems more like 90/10 favoring Horde. So I am at a loss of what to do, I was so frustrated last night at being camped and not getting any kind of help that it almost made me cancel my sub.
