Just wanted to tell you all, that many logs are faked / manipulated at the moment. For example look at the #2 rogue for nythendra:
Its a 4:20~ fight length and he uses vendetta 9 times (lol) - with an uptime of 95%

This results in a lower iLvl % performance for all the normal (non-cheating) players.
