Class passives stacking values

[FalconMan]

I've labbed for 20 mins and came to the following maths:
- 1 Assault character in your team = 5% Defense bonus to all
- 2 = 10%
- 3 = 20%
Same percents for 1 Strike Character so it may apply the same percentages as Assault when stacking
Supports give a 10% buff so 20% and 40% for 1, 2 and 3 members respectively
I'm not checking speed boosts and cooldown reduction values that's too hard to calculate
