the problem is that more people complain about "no good servers" rather than making one - get into a group that would WANT to help you make a gamemode (unless you can do it yourself)
the more people complain about no good servers the less good servers we will have in the first place because they're too busy complaining on how horrible blockland is and the community/servers/etc - if you want to make a change, I suggest you actually make one, not make the problem larger to deal with
