I agree with Nullist, I don't understand where people get the idea from that Penals lose to Grens on a 1 on 1. Penals are actually better than Grenadiers and win frequently against them. The problem is their price is just too high. Once Panzer Grenadiers hit the field they're pretty much worthless if you went Penals early game.
On topic:
I think Penals need a price decrease to make them viable. At the moment their manpower cost is just way too high.
