Hi Pierrette
I don't say it is a good idea to nerf damage, I just second the effort to rework the affix system in its entirety, which is a chance to make the effects more consistent and intuitive.
If you take a closer look at my previous posts, you will notice that I try to analyze what different aspects contribute to the imbalance you and Lou observed, and to give a few suggestions what could be tweaked. Please note that I'm not contributor, and I have not played for a while, so I cannot judge the current or upcoming state of rule balance. I'm just writing as a player who has done some extensive testing a few years ago (before you could even read what the affixes do). And I still think the idea of multiplicative vs additive stacking could be interesting to discuss, maybe I'll open a separate topic for that later.
tldr: I think it will be important to repair the high-end combat balance at some point, but it's better to get the needed ingredients first. PvP with super rare items is broken anyway, also if you keep the current affix rules, right?
