Evaluating archers.

And you wouldn't argue about which one is stronger, would you?

Of course not. Elves are naturally stronger!!!
And there's no need to compare them one-on-one. There are always more of them. Elves are often given to the hero. Elves are cheaper. 14*(3-5)*2=84-140 versus 4*(16-20)=64-80, and that's 140 damage against 84!!! How?
