Lets think this through relative to the initial patch 2.6.7 notes. In patch 2.6.7, they are nerfing both wizards and necromancers who cleared 144 and 142 in non-season. They buffed barbarians which was needed given their top era clear is 133.
They should also buff monks.
Balance may be difficult but it should be the goal. Having overpowered classes does not increase the fun of the entire playerbase.
Was the game more fun for barbs in season 1 or season 2 where they were not part of the 4-man meta and pathetic in terms of power in comparison to marauder DH? The class that I played most was DH. That maruader DH build needed to be nerfed for the overall good of the game.
I have never said that barbs should stay bad. My suggestion is to simply decrease the lamentation rend buff from 150%-200% to a flat 100%. Do you honestly think making that one change will make barbs “bad” given all the other buffs? Your hyperbole does not persuade.
