I can't make formal matches due to no Mirc, but I have high skills and would be happy to show/use them against anyone. Most don't want me to join because of no Mirc which would therefore keep me from matches, tryouts, etc. My suggestion is there be a easier way then irc to "Talk" such as on the menu or added in some way into gameplay like "Private" chat. I understand why you might not do this because then you would need block settings and all that, but it would be easier then having to get on irc. Also clans could hold their own chat rooms. If needed you could have a filter with kicking
and all but I don't think that'd be necessary. If nothing else please take it into consideration.
During matches it could also help with "switching out" people if you know where and when the'll be in the "Quick And Easy" chatroom. Not that Dp2 is based or ever was based on chatting, but you ge the point.
