The nerf the Lasher actually warrants

[Seer]

I collected actual data on this and this is what I found. I will assume for the sake of simplicity that TTKs and all other values except ammunition are balanced. I'll also ignore uncertainty and uncertainty propogation.

For the Lasher to expend its magazine, which is half of its box:
Test 1. 6.34 Seconds
T2: 6.34 Seconds
T3: 6.43 Seconds
T4: 6.31 Seconds
T5: 6.30 Seconds
Average: 6.36 Seconds

Per ammo box damage potential is 2*6.36, 12.7 seconds of fire.

For the Jackhammer to expend its magazine, which is its entire ammo box
7.87 S
8.04 S
7.70 S
8.00 S
7.86 S
Average: 7.89

Per box damage potential is 1*7.89, 7.89 seconds of fire.

MCG to expend its magazine, which is two ammo boxes
11.57 S
11.51 S
11.74 S
11.63 S
11.69 S
Average: 11.62 S

Per box damage potential is 1/2*11.62 seconds, or 5.8 seconds of fire.

So in this light--there are a lot of other factors, like the VS inability to scrounge up the rarer energy ammo and the TR ability to finely govern their ROF--Krisanth's proposal sounds reasonable. However, the Jackhammer's ammunition would have to be further decreased to 13 to bring it in line with the others.

Also to get the full damage potential of a box of ammo the vs have to reload once. The nc don't have to reload at all, and the TR only have to reload once for every two. That's a strength you might be neglecting.
