I was reviewing some of the reps and I noticed something I do not think most people know. If you pay attention during the game, units of "description" changes based on the number of deaths to obtain. For example, the most kills the individual unit that also makes money "range”. Highest rank = superior attributes like attack bonus +1 / 2 or 1 / 2, etc. depending on the unit crest. I think it's a great ideal range blizz incorporated making unit and range up to + kill attributes.
