Well actually, looking at screenshots can normally judge whether or not the gameplay would be good especially when it comes to the size of the map.
I don't know what goes on in the public servers because I very rarely play on them. However, when I am actually playing some pub I don't really see any arguments at all. The only thing I see are "HACKER HACKER HACKER!" and "LOLZ YOU'RE SUCH A NEWB. LOLZ!" But that only happens once in a while and there is either no response to there retardedness, or they get 1 maybe 2 sarcastic remarks back and it's done with.
In the match servers, when you think of how many matches have taken place over the past 4-5 months, there really hasn't been many complaints at all. For example, Team Insane's record is currently 219-38. That is 257 matches, and overexaggerating I have seen maybe 8-10 complaints on the forums towards something another clan did in a match. ch1ll has made maybe 4 complaints about something another clan has done. And that is only 2 clans. Yes, I know clans like Ij, eR etc. we are having problems with. But other the past 6 months there have been many clans that have been respectable throughout that time period, that I personally and I'm sure many others have not had a problem with. Teams like ch1ll, Insane, eR33t, Redemption, CC, MeMi, DoP when it was stil around, Crossbones, and rP have all had many matches with eachother with minimal problems. Why? We have played this game for a while (most of us) and with the exception of a few of people, are the most mature. Sure there is things here and there that may cause something that another clan doesn't like, but nobody is perfect. It's the clans that are continuously being caught for hacking that is a problem.
I think the childish excrement on the forums (which yes I know I have personally been a part of) and the bullexcrement on IRC is what needs to be fixed to help this community. For me personally, somehow more people that play this game coming on irc and clanning is what is needed most.
As for people being glined on IRC. I agree that taking over channels is the stupidest thing ever. I don't know why people do it. It is pointless. They know they will get glined, it really serves no purpose whatsoever. I have asked people before why they do it, and they said "cause I'm bored and it's funny" Sounds like a great answer to me. Then because they are glined, and they now evade their gline and it's a continuous process until their gline ends and they are off a proxi.
I don't know why I spent the time to type all of that up considering I haven't played this game at all in probably 2 weeks and won't be playing anytime soon. That's what I have seen over the past half-year and that's my opinion.
