I have found that the spirit of the gameplay has improved for the most part, just look at 200 in EW or MW a lot of and GF.-SIK1
I've seen a few more, too...but I realize, that it's simply because more of the older hands are flying the EW. I'm seeing just as much trash on 200 as I've ever seen in the old MA. Just splitting into 3 arena's won't change a persons' mentality; And the additional fact is, trying to instill it through a PC monitor is only going to add you to a person's insult list. A PC isn't gonna jump up and kick the ***** out of you, for insulting somebody on ch.200, and people realize that the worst that might happen to them is a warning from HTC, or a loss of radio privileges. Nobody's afraid of getting squelched. It's not like going out in public, like a bar, or a hockey,football,or basketball game, where the insulter might get a bloody nose or a black eye. All you can do is try to use your calm and wit, show that it is a community game, and not just an AI without soul or emotion.
