Not only should there be more good servers but also more good gamemodes as well.
Gamemodes are a very valuable part of Blockland and they encourage people that do not have any coding knowledge still to be able to host a server based on someone else's code.
Sadly not enough players are releasing gamemodes in the gamemodes forum. Sector E is my absolute favorite gamemode and it was released like, what... a year ago?
I'm also pretty salty when people host servers in scarce timezones with very unique code and gameplay, then decide to shut the servers down for good and never release the gamemode they used ever again (I'm looking at you, Pload.)
