This is why I don't get the emphasis on Win Rate

Lert:   You really don't understand statistics, do you?   Let me put it this way: if I buy a new tank and lose my first battle in it, then look at my WR, it'll be 0%. So apparently, according to you since sample size means nothing, this means that it's the absolute most terrible tank ever, right?   Sample size is everything. Even 100 matches is not really enough. At that level any one match won or lost will still mean a whole % up or down. But between 50 and 100 matches, trends start to become apparent.
