I also fell into the neovim pit of plugin horrors. The good news is, you can get out, empty completely your config (or rather, go back to vim) and start from scratch with only what you need.
(I now make sure that my config works equally well in vim and neovim so I don't have to worry about the odd server with only one vim)
