I would rather be at a fun server with a decent build than a laggy server with a really detailed build.
There are very few that perfect this. Cucumberdude always hosted great servers and the build was never amazing. It was less laggy and more fun to play. I wish he hosted more often. I remember his VIP game (a medieval build with an assassin and guards protecting the VIP), his yellow zone jail, his TDMs and free for all maps like Crossfire, Symmetry, and Core. He also had a shield-type TDM where you had to destroy a power generator with a sword to open a room up with the team's core and once that was destroyed, your team wins. None of the builds were amazing or super detailed, but they were all very fun. He even had a free for all and TDM arena where you could choose which map you want to fight people in, buy new weapons, set up team battles, spectate an arena to watch people fight, sit in the lounge and visit with friends and even set your own team channel so you could team chat with specific people. Cucumberdude is my favorite host.
We need more servers like this. When I go into a server, I care more about the game-play rather than the actual build.
