If SE listen to feedback, then future Eureka content could actually work.
Most of the issues that turn people away from the place are pretty easily fixed. It's just a matter of will they bother to fix them? Will they listen to feedback?
That said, I'm still very confused why they don't just... You know... Make Overworld not suck... Since that's all Eureka is. Overworld. But instanced
Boggles my mind that they didn't just have a level 70 zone with all the bells and whistles that make Eureka "Fun" (I.e. Cross-Server play, powerful NM's, some actual worthwhile rewards from doing FATEs...) but without all the unnecessary garbage that sucks all the fun right out of it (Random independent leveling system that serves no positive use, damage and health scaling on enemies jacked up to 11 mimicking DS2's worst DLC, no actual rewards through non-FATE based means... FATEs having terrible spawn rates outside of farming mobs for ages to force them... Oh, and Light Farming because who doesn't love that /s)
But I dunno... I guess we'll see how things pan out. Eureka as a concept isn't bad, it's essentially just having an Overworld that's actually relevant, which is actually really enjoyable when done right (Guild Wars 2 had some pretty great overworld content both for PvE and PvP. As did Warhammer Online. Rift too, but then again, I'm a sucker for puzzles... Both jump and otherwise). It's just a matter of, will they learn from this and improve? Or will they just copy/paste Eureka as is post nerfs and call it a success?
