Protip about Eureka. It’s not that bad. Get the instance to spawn fates. Don’t worry about level. and viola, glamour.
I mean whether it’s bad or not is all based on the person participating. Personally, I won’t be going into it because nothing is more boring to me than grinding mobs for hours on end for glamours that already exist in the game and can be obtained through much easier means/ilvl gear that isn’t even cream of the crop, but I also don’t care enough to actually complain about it.
Its basically like the Orr train in GW2 now so its not so bad. People are now getting groups to hunt specific NMs, which is WAY better than just spamming the same mob for hours.
