We're making an adjustments to the clan winnings from an attack: Ally winnings will now also be based on relative strength between you and your opponent. In the wars, this was being exploited by high level attack builds farming weak builds and still making lots off their ally bonuses. Attacking players around the same level (people on your fight list with good reward) will give you slightly more bonus as before. Attacking higher level players will give you more bonus (we've raised the bonus cap) Attacking lower level players will give you less bonus.
We would just like to clarify - you will make around the same plunder from allies as you did before. However, your reward for attacking more powerful players will increase by a significant amount and your reward will be less if you're attacking players much weaker (3-4x) than yourself.
