Is there any point to doing Relic Weapon quests other than glamour?

[Ashkendor]

I did the quest originally because I was under the impression the relic weapon would be continually upgradable. I recall reading that in a developer interview or something.

I know that I have no intention of investing time and energy into upgrading a weapon that will be abandoned for a new upgradable weapon come next patch. All the time I sunk into it could have went into leveling another class or something.

You do realize that the original relic quest lasted from 2.0 all the way through Heavensward, right? That's two years. You don't need to worry about the content suddenly becoming obsolete "next patch". More like next expansion. Zetas also stayed viable for leveling until around 55-57 and got you past the hideous "Atma grind" stage of the new Anima weapon quest. Not bad at all.
