Exactally. I hate "[generic minion level 2] is more powerful than [generic minion level 3]". Umm... Duh? LoL.
Edit: To be more clear, I specifically want to know how much "minion damage +5" actually helps. From watching health bars very carefully, for very low level units this seems to help a lot, leading me to believe that level 1 minotaurs seem to do like 10 damage vanilla, but it's difficult because you very very rarely have one grunt attacking one other unit for long enough for you to actually figure how much damage yours is doing to theirs.
