100/200 server limits way to strict

I'm using Nitro and have a 200 server limit, but this is still way too strict for me. I find myself having to leave a server each time I want to join a new one which is very problematic. My only current solution is to use multiple users, but this is very inconvenient. Would be great if server limits will be increased, or at least if there is some additional plans that offer higher limits.
