I built this to somehow kill Champs in WoE. It's not OP because:
you need to bring traps (that are heavy)
you need to drop the trap (which needs a lot of experience and technique in order to properly place your traps)
the damage doesn't do much. although to some jobs, it will definitely kill you
if someone is near you, you can't trap. hence, a way to counter this is to get near the Sniper
I don't fine it OP
go back to #5
