Since we have 4 hunters for each type that can mix up 256 variety. But monster have only 4 types that can spend just 9 skill point at stage 3. So I think they should have some more skill to combine and make it more variety and much more different play style. You can now chose 1 from 2 in each skill.
Ex: goliath : you can now build him as sharpshooter or real close fighter.
- rock throw / rock roll : like behemoth roll but with rock
- flamethrower / fire aura : Goliath now have flame aura that burn everything around him.
- rock wall / rock skin : forget about hole in the wall now he could build free armor for a short period of time.
Kraken : make him a new comet battle style that focus on attack from the sky.
- decoy / skin molt : wraith teleport to target location and leave decoy at using place that have 1 single attack to hunter then disappear. also gain invisible for a period of time.
