Cam Im assuming its just from the increasing stats, as well as more spy stats. Assassinations do a lot of damage and ony payout in the bonus. Attacks do a moderate amount of damage, yet pay per action, and in the final bonus. So when more spy builds arise, more damage with less pay. I, for one, can hit with the attack and assassination damage of an hlbc spy and an hlbc attack, simply because of my equipment.
The devs should release an item for war beasts that is extremely rare any gives an instant 10t a hit on everything and you can 1hit KO any EB
Those who are saying the plunder is not going down and are saying that it appears to be less because of more damage are wrong. The plunder for Haunting HAS gone down. I noticed rather quickly because I track how much money I make on a haunting and it has decreased soon after the t5 release. So Yes the plunder has dropped for t4 building players/hansels.
Recapping.. Both have decreased, devs said plunder was being tweaked, and equipment and t5 increase the damageay per hit ratio, lowering total haunt plunder.
They did not nerf haunt. It depends on how many people are in haunt, and how long your clan does the haunt, I've seen clans get 100b in haunt.
