I like voting for maps that people don't like, just to annoy them (thanks for the Thorns tip, Warden
).
TWD - man, I just think you're missing two points:
1) Different people have different tastes. Just because you or others don't like a map, that doesn't mean everyone hates it or it's automatically a bad map. For example I for one think TechDreams is a dang fun map, and I'd play it 2 on 2 or 10 on 10. However, I know not many people like it. On the flip side, if I was to decide every map we played on my own, I'd NEVER vote for Romra or Bollwerk. I hate playing these two maps. However other people like them. To voice your opinion like "ugh, Lavagiant? I don't care for this map" is fine, but if it gets the votes, then sit back and play it, not being critical of others for voting for it.
2) Sometimes a change of pass is good, even if it means on a bad map. As Raffi said, the same maps over and over and over and over get a little tiresome. Sometimes I'll vote for a map that I know we haven't played in a long time just for a different look, even if I don't like how the map plays. Heck, I'll even vote for a cube if I feel like a spam fest (which is all Romra is, btw, but that's another rant
).
Everything's fine the way it is, dude! Just sit back, relax, and have a Coke and a smile!
The only thing that removing various maps would do is take away maps that others may like or enjoy just because a few don't think it's up to par. Remember Sat night, we played that one map (Coret was it?) that everyone was like "Man, this is NOT a good map" and it actually turned out to be a very good match. Yeah, it was on a sub-par map, but so what? The match was fun!
