Burzum, that's why you are the Head admin, you chose as the last person. We can only tell you what we think and our opinions would differ.
As I said you have 2 choices.
1. Classic server
Only classic maps which are
de_dust2
de_inferno
cs_assault
cs_office
de_aztec
These maps by far are the most popular apart from all the other maps.
2.Public server.
Variety of maps.
I suggested to have small maps like fy_pool_day and fy_iceworld (no remakes) for admin choice only if the server has only few people in it.
awp_india is a popular one.
The thing is to keep the server you have to go to popular than having the maps people don't want to play on. I understand some of the maps are good and I like them too, like de_prodigy, but there aren't many who like that. Stick to popular maps and now and then throw a map which isn't played often, it will spice things up.
Burzum, assault maps aren't that popular, yet you see few people want it, yes they do, well they aren't the majority. You have to look at bigger picture.
