It's a high rate server theres hardly much of a catch up, I started leveling yesterday i done from 43-60 in a few hours just running through ST maze then to ST KR yhen back to maze vice versa
I'm going to take a shot in the dark and say you've been playing Mir previous to your 2009 join date, thus I'm positive you understand rates actually mean nothing. One week into a standard euro rate server vs one week into a "high rate" server is still one week into the server. The catch up the same regardless.
