I don't like the voting much in general to be honest, not only on CTF. Here's why.
CTF:
Lately [since 2.3] I have been leaving servers sooner then I was planning on beforehand because of
another game at Facing Worlds or another crap map. OK, Facing Worlds is not a 'crap map' but it does get tiresome after two games or so. Like any other map that gets played too much I guess. I don't have a gripe against Facing Worlds but more with the way a lot of people seem to play there which makes it tiresome even faster. How many just grab a nex and snipe... well, get sniped really on the side of the tower. It all just seems a bit silly. But I'm straying off topic here but the essence is that I voted for No with that reason.
DM:
And in CTF most of the people know the maps by name because most of them are named pretty convincingly. But in DM/Minsta a lot of maps that are not in 2.3 itself have very arbitrary names, slightly random letters and numbers... I have played a lot of Nexuiz the last year and STILL don't know most maps with their names, other then the standard ones so another problem occurs. Even if people don't know what map Aggressor is it easily wins over a map that can not in any way be judged by its name. An d that is fine
every now and then because it's a great map... but it might get frustrating when you want to play non-standard maps as well.
In general:
There is a problem with it that also goes further then "people vote crap maps". I mean... if the majority of people on the server are voting for crap maps then clearly the majority of people on a server want to play crap maps... and if the voting is to be untouched and an outing of our democratic intentions then it works perfectly. But we DO end up playing a lot of crap maps

Some of the players, probably the most vocal or Nexuiz-experienced ones, do not like that and start trying to change it. Which is fine I guess but devalues the voting system. I have seen the following scenario's played out multiple times already on different servers:
1. People on server vote 'crap map' -> others call a vote to get rid of it... a lot of people still don't know how to accept/reject a vote or are too busy starting the game to care [despite of the annoying stuff on screen whenever you have not voted yet] -> map gets changed.
2. People on server vote 'crap map' -> server admin changes the map.
Where is the democracy in that ?
My suggestion ? Ditch the voting system as a default and bring back the map lists as the standard way of doing things. Keep the voting as an option for those server admins that want it.
If this all just sounded like a stream of random thoughts... it probably was.
