Might be a silly suggestion but as of now I feel like barbed wire doesn't have too much counter-play aside from frags and blowtorch. What if attackers had 2 or 3 wire cutters in the arsenal they can use to clear out barbed wire.
Another idea I had was to buff the blow torch and give it more ammo/make it melt barbed wire faster. I feel like the blow torch is really niche in terms of when it can be used so this would give people more reason to bring it in.
What do ya'll think?
