Endgame Confusion: What to do, what to skip?

[kuma_aus]

I was actually wondering if the relic weapon you get from the questline that starts at lvl50 is still viable or outdated now?

It's outdated. For level 50 content, the final relic is good, but that's maybe like 3 months of grind when you can easily get a slightly weaker weapon like augmented Ironworks in less than a week.

The only part of the Relic that is still viable now days is the first quest I would say. Doing it unlocks 2 new trial fights which is not necessary but it's good to have unlocked if you're a completionist. Those 2 fights are in Trials Roulette so even if no one is doing those fights, people doing roulette will still team up with you to clear them.
