recently it is quite often to run into people using 3 types of hacks:
1. granade barrage
2. infinite health
3. granade with extremely big radius(basically whole team takes 75% dmg)
@Skitrel here are the chances http://en.wikipedia.org/wiki/Risk_(game)#Dice_probabilities ,losing 4vs1 two times and 7vs1 makes me think only shit happens rule works here
@Abalore give some info about armies clash system. I've seen too many 7-unit armies losing to 1u armies to belive everything I know about propability and Risk isnt just bullshit.
