I understand why the raiding nerf was made, and agree something must be done; however, what has been done is wrong.
The question which no one has answered is one I have not seen asked: what exactly is it the devs were/are trying to do?
Most are saying it is the game is growing too fast, and that stems from asset inflation. Okay, which assets?
From the lower level of platinum-tier to the bottom rung, it is resources which build bases and strengthen rosters. The higher ranked players seem (not there yet but paying attention) to be chasing mats through opening richer chests. If this is true, the nerf did not address the second possibility which hss created a true two tier game.
As an aside, the devs created this problem not by giving us the raiding sustem but by giving us the second builder. That beast needs to be fed, and raiding greatly increases that foodstock.
The only way I see any fairness in solving this problem at both levels, is through the chest-opening mechanic. If a players raid below their tier, penalize them.
The raid chest would stay the color of the lowest level raided, or that lower raid could gain resources but not add to the chest or both.
This is my suggestion to start dialogue.
