So in the patch notes they have added a good amount of challenge log entries that are designed to give you elemental exp, depending how much exp they give (which is based on your level) it might become much easier to cap, from the interwiews they alluded to some treasure hunting to be done inside too.
This is where imho the good news stops, because then they added that pagos will only allow us to upgrade the weapon but not the armor, which imho is a terrible chice and also a terrible prospect to those that actually invested time in the zone, there can be many explanations on why it's not done, like they don't want to sacrifice the 24 man too much, but with the greed only loot first and the surely coming 4.38 unlocking savage I really don't see why this isn't a thing, especially considering the fact that pagos is coming in 4.36 which is probably 1 month and half away.
As said the "life" of a content/game is given by the support it recieves and imho atm things are not looking good for eureka, but this are just my 2 cents
