mele HH with mega power fist can easly ko to death 9999hp takn with 20/90% resist, only way to kill mele is 1hex him or shoot him at distance. 1hex bg/gatling is very powerful and in your face is perfect perk to avoid it na ko to death bursters
toughnes/even tougher are fine like it is. you dont need trsholds for ew or plasma, becasue they are aim crit weapons and gatling have 50-100 base damage, so it wont make difference
2x tough nad adr rush + psyho is perfect combination vs avengers and if for you toughnes is ules play "Tank" without it and you will see how many damage can dead 3xbrd avenger burster
