Onslaught is the new feature and there is a severe flaw. This pic shows why:
In summary, we somehow matched a 1 person faction. The rules of Onslaught is that everyone gets lives, when you lose your lives, you can’t be attacked anymore. Inexplicably, you can still attack when you’re dead.
The flaw: we can’t attack this 1 person anymore however they can attack us as much as they want. So a 1 person faction can easily beat a 30 person faction.
