Thanks for the info guys and girls! I too was wondering that. I get this hero and I'm like omg this guy or girl is a pimp! And then after a few lvls I jump in the statitics section to compare ... and umm, yea he/she is ranked like 56.

I, too was baffled when I saw a hero with an 86 stat at lvl 3. Can it really be from one of the rewards? Does that temporary buff get taken into consideration and added in the statitics?
