Re: Mastiff the worst shotgun?
It still can deal 33 damage on range of 30 meters. I treat it as a shotgun, but with longer range, in case of which you don't need to wait for the precision choke while aiming.
Then, the slightly lower fire rate won't hurt you, and you can deal damage safely. It may be somewhat useful, especially, if you have a lot of ammo.
I think not everyone likes to decrease the distance, if their shield is already damaged, so it can keep enemies at bay that way.
But yes, if you are extremely close, low rate of fire makes it weaker and its easy to loose to SMGS.
I prefer to use EVA-8 all the time anyway. 🤔
