Cave knights a bit too powerfull?!

[Sombre]

In MP games I don't think Cave Drakes are considered very good. They certainly aren't worth 10 gems, because there's no way a cave drake is actually worth 8. The reason building them is better than most early summons is because early summons on the whole pretty much suck.

But bless troops and combat magic go through the drakes pretty easy. Bless troops because the drakes have no chance to hit/hurt them, combat magic because it can often ignore their prot.
