As of March 11, assuming EJ killed Illidan every week since July 29, that comes out to 32 weekly kills

As far as I can tell, those results are well within what could be expected. They are on the unpleasant end of the scale but they are nowhere near being fabulously unlucky (if, for instance, we assume the 3% droprate is closer to the truth, one warglaive in 32/33 kills is exactly what would be expected on average)
