Six hours is a lot of time to spend testing. Most people would prefer to “test” by just playing a bit then cherry picking the things that confirm their biases. Even of those willing to invest that amount of time in rigorous testing, most are probably on rated teams that keep the information to themselves to gain an advantage. Then there’s the fact that the scaling system is now sufficiently complex that even six hours is sufficient only to test one set of circumstances.
Sharing quantitative results on the forums is an exercise in futility anyway. Last time I did that it was on level scaling, and I was shouted down by 120s who just wanted to pwn noobz and hated the level scaling that gave people a level or two lower even the slimmest of chances against them. Blizzard of course listened to the whiners with the result that it’s impossible for a lower level to beat a 120 unless the 120 is AFK, and difficult even then, with consequent detrimental effects on people who might want to level in war mode.
Most people are only interested in hearing things they want to believe, not in learning the truth.
