the strongest, unupgraded unit at level 7.

Okay, fine... The monster isn't that bad against flying units... It performs quite well in close combat. Not worse than giants... The monster attacks well, but in other respects...
Here, the question is posed from my personal perspective: should I take this unit in the Nomad camp or somewhere else, like in a similar location? I would take the Devil and the Angel. But regarding the Giant, Hydra, Skeleton, and Monster, I'm not sure...
But still, don't criticize so harshly...
