PowLvl Formula (WIP)

S
Sustain

Dp
Damage potential

Ar
Attack Rate

N
Number of hits suffered in average

Me
enemy model count

Mf
friendly model count

oAmax
opponent Attack rate maximum

oAmin
opponent Attack rate minimum; assumingly

Suggestion
S*Dp

Dp = Ar * Dmg * (Acc+WM)%

Ar = (Mv/5 + Rng/5) * 0.5(Amax + Amin)

S = HP * N

N = Me/Mf * 0.5(oAmax/Me+oAmin/Me)

Conclusion
HP * Me/Mf * 0.5(oAmax/Me+oAmin/Me) * (Mv/5 + Rng/5) * 0.5(Amax + Amin) * Dmg * (Acc+WM)%
