Evaluating archers.

Orcs just aren't very good with their hands... :)

Lizards are excellent warriors, dealing 2-5 damage when upgraded, i.e., 3.5 on average. Storms deal 4, and marksmen deal 5.

It's better to deal 2-3 damage twice than 2-5 damage once.

A subtle hint - so position them in a group.

Position them in a group for the sake of the Arcomage? They die before that happens... Although, it seems to depend on the situation.
