Claymore seems weak to me.
I’ve been leveling in party with Peltasta, which helped me get monsters where I wanted them.
In comparison to Punji and Barricade traps, Claymore felt just weak. I had +10% damage from passive, and maxed out the range passive. In terms of damage, they are about the same, however Cade can be used to hit monsters multiple times, and Punji has bigger AoE (though it can benefit from it only with help of Peltasta). Not to mention both traps being much much cheaper in comparison, especially Punji after last price reduction. And you have to walk to Sapper master to buy Claymores. Also, I might be wrong on that, but I felt like it can only hit set amount of monsters.
In my opinion Claymore should get a damage increase, maybe something around 25%.
