I would say yes as you don't mind a long grind. They tend to look really nice and are always the strongest weapons by the time they are done (at the end of the expac so that a bit of a moot point but still). I have done every relic quest line and usually enjoy them just be prepared for a huge time investment.

Also I like that that are strong enough that I don't need to upgrade my weapon until near the end of each new expansion. This has aloud me to make so nice gil selling the weapons the MSQ give you for free since I don't need them until I'm 1 or 2 levels from max
