It wad actually slower to kill someone with the 100HP and the damage increase update
Since all the dmg of the guns got doubled minus 1-2
So let's take the snobnose as example
Normall damage is 6 and it takes u 9shots to kill someone
With the damage increase on the snobnose will deal 10 or 11 dmg
And it would take u 10shots to kill someone with the increased HP(100HP)
