To be fair, with the current Ranked season presumably being the last, it doesn't really matter if the Relic is BiS or not if all you can do with it is make worthless Exarchic gear. It's basically just glam, even more so than the combat Relic which at least is worth it for Savage both last patch and in the near future, especially with another Ultimate coming up.

Not saying that's a good or bad thing, just that I wouldn't do the grind thinking a BiS mainhand will be all that useful unless we get more craft content before 6.0.
