Just putting in a good word for them here. I realize IJ has a bit of a reputation. But I have noticed in the two times my new clan Scrimmed them, and one time my old one did that I was present at, that the parent clan members come and encourage and teach in the practice scrims.
Occassionally an IJ member will hop in during the middle of your scrim, but overall at least they keep things entertaining. And I have picked up some decent tips just listening to their comments to their own trainees.
Oh yeah, and when you match them use a GT advanced or EV1 server as they didn't seem to appreciate gun temp!
