The damage could stand to be nerfed through walls/roofs a tad. It still needs to be a reliable counter to building camping.
Leta say it did what? 50% damage?
If your in there long enough to get downed by getting smashed through walls and roofs, thats you’re fault as a FT for hiding.
As it stands now its rough because that cover is the only breathing room to heal up in moderate safety.
If that damage was fully removed then it has to destroy dropped meds and ammo indoors through walls then at least. Some buildings are the worst chokepoint in 1v4 with a team purposely hiding for the clock.
