the good thing about punx is that the vote can be rocked and many people feel the same way as you porno. it depends who is on the server, but one of the big reasons i started playing at punx was because the map rotation wasn't only dust - dust2- aztec - office. i know for a fact that many other servers on cz just play these maps strickly, the fact that we often play non-traditional maps is what makes punx community so much better than others. i mean how many times do you see other servers playing piranesi...that maps been around since cs 1.3, but i dont complain since each game is different. the punx community seems that they want to play real maps, i suggest nominating more czl/cpl maps - these maps offer a complex setting of boxes and very creative angles, this may solve your problem by adding a new look to your game play... heres some suggestions of maps that i feel are balanced that we dont play that much...
Torn_cz
vostok_cz - maybe...
airstrip_cz
survior
train
cbble_cz
czl_Nuke
Truth_cz
czl_frieght
czl_silo

These maps are all great, except they may clear the server if the right crew isn't on. guess just start nominating some of them, i like airstrip, nuke, and train the best outta all of em'
