There is realy no reason to guess all that. Math is pretty easy really
Give me your base INT and STR and I will do the rest.
I will use this set for Insurgency
and this for Entropy
I will go with 105 base STR and 85base INT
Insurgency WSC:
STR = 190*0.2*0.85 = 32
INT = 130*0.2*0.85 = 22
Total: 54
fSTR - Lets say around 17
162+17+54= 233
fTP - Not much info is given how AM3 works with DA/TA etc. but I will guess that avg fTP will be
3+0.67+0.748+0.1= 4.518
Insurgency dmg: 4.518*233*1.3= 1368
Entropy WSC:
INT: 153*0.85= 130
STR around 162 so fSTR around 7 less
130+162+10= 302
fTP: 3.9+0.73+0.0975= 4.727
Entropy dmg: 4.727*302= 1427
Like you see Entropy easily wins especially that every details that I havent included like overtping/atmacite/braver's will all favor entropy.
EDIT: Ok I was a little wrong. It wont win easily but slightly because I forgot Insurgency build have more attack. For uncapped attack both WS have very similar damage unless you are Taru with INT merits maybe. For VW tho Entropy easily wins because of TP bonus atmacite and braver's.
