yes and no.
pros:
They have high AOE, so yes.
Their damage is enough to kill several raid units.
cons:
rate of fire is low.
raid units can kite and dodge the attack if on land.
Additional bonus, they work well with scalpels:
Claymores are the same speed as scalpels, so they can support each other without slowing each other down.
Scalpels homing range attack can minimize the damage raid's kiting of claymores.
Scalpels also have AOE and can 1 shot most raid's as well.
Probaby best to build 1 claymore to 2-3 scalpels when using this combo to take advantage of the scalpels range.
The other pair that works well with hover is bola/Halberds.
They also have the same speed. Halberds can't hit raid units unless supported by bolas.
Probably build 1 halberds : 2 bola's as halberds have more survivability, and bola's are needed more in smaller groups.
Another pair I use is mace and lances. Lances are just too expensive. It's great against larger defenses, but not so much against weaker artillery, and it is just asking to be rushed/Lichoed. I think a long range com works better as a artillery as it has more armor. Probably should make 2 maces to defend each lance.
When opponent is spiders or jump scalpel/bola's make a good combo. riot/raid units have just a hair more hp then a scalpels damage...
