So I did Burn Out today and went for the balance achievement which was a friend's final challenger for CotF. The achievement is to not let the final 2 named get over 5% out of balance. When we did it the 2 named never went past 3% balance. When we opened the chest at the end someone in the group got Keeper's Imbalance but no Keeper's Balance. I don't understand how we got Imbalance (lose balance by 40% or more) when we never went past 3%. I'm curious how we could go about getting the balance achievement since actually balancing them doesn't seem to be the way to go. Anyone have any ideas or tips about how you got this? I personally got it shortly after this came out and it automatically gave all 3 challenger achievements on a win.
