Really, Ravidge said it better than I could. But I'll say some things too.
When competitive players have nothing to say other than "It's trash" or "Not Badlands" it's pretty easy to get discouraged. I don't know what you guys want, and 90% of my dealing with comp players in a map related context make me think comp players don't know what they want either. And though I haven't really dealt with comp players for anything more than making pro viaduct, I've seen them attempt to give feedback on other maps and it's dismal. I don't mean to imply that everyone needs to give amazing feedback--we certainly don't do that here or anything--but something more than 3 vague words with "idk" tacked on the end would certainly be nice.
Scorpio, your PUG group is probably the most useful thing we have for anything comp related, and I really want to thank you again for it--on behalf of all of us really. But if someone else was running it, I don't think we'd really get the feedback that we get. It takes someone that understands the engine and Hammer, like you, to filter through what comp thinks and says and feed it to us in a way that's useful and makes sense.
I sure wouldn't mind more comp-oriented maps. I think a lot of the ones that exist--like Indulge or Obscure or Follower--just leave something to be desired or are completely bad. I think maps should be able to function well in comp and in public servers, like Badlands, and be enjoyed by a wide variety of people. I'm not interested in making another huge map with a bridge for a mid and I'm not interested in making a map with barely more than a basic detail level to suit comp's misguided ideas about optimization.
I also know that many of the mapping-minded comp players there are don't think much of this site. I think that's probably fair. A lot of the people that make maps here are new, and the ones that aren't aren't concerned with comp or are burnt out. I'm pretty close to burnt out myself. On the other hand, to be perfectly frank, I don't think much of the people that map for comp. They churn out map after map and each of them seems to be abandoned one after the other, with Gullywash maybe being the exception? And few of them, if any, are playable in a public server?
If I was going to map for comp, what I would want to do is probably make a dom map like cp_standin or an SD map. Unfortunately, I don't have access to comp players that want to help with that and somehow doubt comp is interested in SD, even though I think it could really excel in that environment. I feel like even trying would result in mockery. When I read comp players talking about maps on forums or listen to them in games or god forbid talk to them about something, what they seem like is a stoned child intent on throwing a fit if they think that's what their friends would do. And that's terrible. I'm well aware that I'm no angel myself, and I am sure certain people read or watch my interactions with others and think I'm an asshole, just the way I do with comp players. The thing is that I could put that aside. I'm not sure comp can.
Like Ravidge said, if there are some people that don't hate new maps that we don't know about, please let us know. Part of the problem with how bad our maps designed for comp are probably stems from the fact that neither of our groups really network at all, and fixing that is probably the first step.
