Tarryk covered many important points already.
I'll just chime in too, as a DJ!, and add that I have DJ'd some amazing events on RK2. Not just ARK ones, mind you. So I do have a love for the RK2 crowd. I know you guys can party. I've seen it first hand! DJ Ashval
regularly holds his show on RK2.
But, as stated, a big issue is a DJ making an effort to show up on RK2 but not many people actually stop by. It depends on more than just listener ratio RK1:RK2. It depends on the DJ's time slot too. Lots of factors are an issue. Me, I enjoy hopping on RK2, but I am kinda bummed when 95% of the crowd there ends up being RK1 players switching DIMs.
In the end, RK2 will always have GSP's attention, so don't think we value one over the other. As tK said, we were born on RK1 and it's just a bit more familiar.
