I've stuck my toe in Eureka since those nerfs. They aren't enough to get me back in there. The mobs are all still massive hp sponges. I was able to solo single mobs in Eureka when it first launched without any risk of dying. It just took a year and a day. Then there's the whole separate leveling system. When I say "nerfed into the ground" I mean I wanna be able to go in there as a lvl 90 (or higher) and one or two shot packs of mobs with impunity. The experience in Eureka is distasteful. I don't want to be in there any longer than I have to be, and right now, how long I'd have to be in there is too long for me to be willing to subject myself to such an unpleasant experience.
No, I'd rather live without the glams and TT cards (which means I'll never be able to finish my TT collection or certain TT achievements since some cards/npcs are locked behind doing the bulk of Eureka/Bozja) than to spend my precious game time doing things I don't enjoy. As I said, if Eureka and Bozja never reach a point where I can just solo steamroll my way through them at a pace I find palatable, I'll just continue to pretend they don't exist. The aggravation just isn't worth it otherwise.
