It is ridiculous, but when you come against voidstones in like half or more of the games you play, it becomes a huge disadvantage not to have one. I’m pretty sure my 380 lfr voidstone is better than anything that’s not a better voidstone.
Hopefully stuff like this makes blizzard realize how bad their decisionmaking skills are. Like hey, let’s make a trinket that drops from pve that isn’t even good in pve but is basically mandatory in pvp. That makes sense
