so, i tried to time the cooldown and reload between shots and got about 4-5 seconds in a stand up, cover to cover fight. (because cohstats.com is just a bunch of jumbled numbers to me :/)
Would the buff put rifles at firing a round every 3 seconds or so then?
[(Reload Frequency + 1) * Accuracy * Damage] / [Ready Aim Time + (Fire Aim Time + Cooldown) * Reload Frquency + Reload]
The dps formula for rifles. Assuming 50% decrease in reload and cooldown for the M1 garand, and at say medium range, thats:
[(8+1)*0.55*10]/[0.25+(0.3+
1.325)*8+
1.5]=3.355 dps. The underlined numbers are the only numbers modified by the 50% decrease in cooldown/reload m1 carbine ability. Plug in the numbers, stick it in a calculator(I used wolfram alpha), done.
By comparison, the garand without the ability does 1.79 dps at medium range. So its roughly a 86% dps increase.
Some numbers.
[(8+ 1) *0.35*10] / [0.25+(0.6+ 2.06) *8 + 1.5]=1.367
[(8+ 1) *0.75*10] / [0.25+(0.075+ .756) *8 + 1.5]=8.03
Garand dps with the ability at long/medium/short range: 1.367/3.355/8.03, Garand dps without the ability: 0.7674/1.79/4.232.
So roughly a 85-90% dps increase in the garand.
MG dps formula:
[Rate of Fire * Burst Duration * (Reload Frequency + 1) * Accuracy * Damage] / [Ready Aim Time + (Fire Aim Time + Cooldown) * Reload Frquency + Reload + Burst Duration * (Reload Frquency +1)]
Bar dps:
[7*1*(7+1)*0.2*7]/[0.1+(0.25+1.75)*7+1.5+1*(7+1)]=3.32
[7*1*(7+1)*0.45*7]/[0.1+(0.25+0.875)*7+1.5+1*(7+1)]=10.09
[7*1*(7+1)*0.75*7]/[0.1+(0.25+0.393)*7+1.5+1*(7+1)]=20.849
Apply a .75 damage modifier vs infantry from the bar:
Bar dps with the t4 l/m/s: 2.49/7.56/15.636
Bar dps without the t4: 1.533/5.069/11.385
So only about a 50% dps increase with bars.
TLDR:
DPS of Riflesquad(no bars) with the t4 vs infantry armor long/med/short: 8.202/20.13/48.19
DPS of rifles without the t4: 4.6/10.74/25.39
DPS of a BAR riflesquad with the t4: 10.448/28.54/63.292
DPS of a BAR riflesquad without t4: 6.136/17.29/39.67
For comparison, this is the dps of a four man mp44 squad: 4.1/15.664/77.76
Dps of a single LMG gren squad 8.25/16.3/33.09
This ability is extremely good with vanilla rifles, and still decently powerful with bars. It does not improve rifle survivability any, so all the regular rifle counters still own them. It takes good micro and flanking skills to utilize properly.
But with the current numbers(50% cooldown and 50% reload), it lets you have extremely powerful unupgraded rifles. Though keep in mind something like a KCH squad will probably still facerape you with its heroic armor.
