Well to be honest knowing SE we will have Eureka 5.0 so I just hope a couple things happen.
No more level lock on certain things like mounts and aetheryte crystals...Pagos is a huge example of what not to do ever ever ever again.
The things you did right, not needing to be on one specific class to complete a weapon, that had always bothered me in previous relics.
The community isn't all that bad in there, but here's hoping SE learns from their mistakes.
