In Shadowlands, Blizzard are "fixing"/restricting rerolling of RtB by slapping a CD on it. But why were we even rerolling in the first place? Because some of the buffs are much stonger than the others and they still are. So Blizzard haven't fixed the problem at all, they have instead just restricted the solution. Our damage are still going to fluctuate a lot based on RNG. And they have even added a soul bind that has 7% to reset the CD of RtB because they know players will want to reroll. Blizzard always do this. Instead of fixing the problem they just limit the solution. But the problem is still there.
