Most of the deathmaps need some balancing before they should be added back. I still don't see why the maps arn't sorted in alphabetical order though, that would help with the map-spam problems.
We used to play them in alphabetical order, then the server started to crash every 4 - 7 rounds, idk what happened, but 1 or 2 months later you could vote.
I would like it to be like that, but i don't know what the community thinks.
Edit maps then. Make it more fair.
Some maps, humans die in wave 3, and on others, you stand watching someone for 7 rounds in a corner just being able to take damage from poison headcrabs.
But editing then would kind of kill them... maybe just fix the doors in deathgarae and that place were you can press a buton, get on top of some crates and only poison headcrabs can get you?
those are the only 2 fixes i think should be made... and maybe some ammo crates.
