No, for me the sample is enough to draw conclusions. But there would be people like you that would actually say "sample is too small". My conclusions are just not formed from this actually recorded incidence, though. They come from my total WoD experience. The mentioned fact comes just as a weak argument for the conclusion. As a funny fact, tho, i just came to read the thread after missing the same mission on my only alliance toon at 89% (can't keep tabs on 10 chars, so no records on the rest of them)
