What is currently happening is equally/less hardcore players actually being propelled up more easily than their higher-level counterparts, so the “shaking” is slowly resulting in an unfair distribution or an unfair effort, based on the beholder’s eye.
The solution has been mentioned before by players in the forum, and is easily implementable due to the fact that we can face players who are not in our bracket: everyone gets a low/med/high opponent option for every battle, with the possibility to create high-level opponents for those end-gamers at the very top levels.
We saw such created accounts in our brackets when this new PvP mode was launched, so it’s not a new approach. ( [Known Issue] Everybody has the same enemies in Pvp ladder - #2 by panda-zebra )
