Please no more Eureka!

[Reynhart]

That weapon is only available to you, especially in the upgraded form that will allow you to solo things, after you've pretty thoroughly exhausted Eureka and likely have little reason to return unless you really want another glamour piece. It's not going to help people who go through Eureka for the first time next expansion.

Almost as if the Raid weapon is only dropped after you already beat every floor of the raid...I guess it must be badly designed too.

At the time, they were BiS (random Diadem drops aside). If you just want free glamour pieces, there are plenty of ways to add those without degrading the relic weapons.

Except that, if you go up to the final weapon/armor, those will always be the best items in all four zones of Eureka, allowing you to farm other Eureka gear faster, as opposed to the previous relic being overshadowed by merchant gear in old content or being ilvl synced back to where you started in current content.
