well, thats indeed something that worries me at times. you know, i do defend the need for an eternal realm, but stuff does indeed change quite heavily balance wise from season to season, which of course, doesnt make too much sense when we talk about eternal per definition.
Considering the amount of class balancing that happens after every season, i kinda assume we will face a point where eternal needs a seperate kind of balancing, since this realms only relevance is for people who dont have enough time for a season, and just want to enjoy d4 in their extremely limited time.
