I disagree. I think the multi tool should be left alone. It shoots fast and hits like a truck. Easily my favorite gun. Some of the fire rate perks hurt the gun in my opinion. I'd rather have voc shoot faster but stay semi. I think the Suros is better with a steady rate of fire. I hate that it slows down. I have a second Suros that I will not upgrade because I like it shooting fast down sights. It would be cool to choose a rate of fire perk like the ballistics.
