For me caps suck because of this:
I logged in tonight to find the Orange arena maxed out. No biggie, I went to blue.
Blue arena had a single fight going on for me to participate in.
After trying to get into Orange a few more times I made a comment on country to the effect of,"This is why caps suck, I'm forced to take part in a fight I have no interest in." This was followed with the standard idiotic, "Go outside" and "Nobody's holding a gun to your head." comments.
So I just logged. Now I'm typing this and having a cold one. Guess I'll try again later.
