This Novus Weapons Quest... Nnnnnhhh...

[Kanemano]

Because

1. Relic has always been an optional side quest
2. People asked for a grindy quest (start of 2.0 era)
3. Although it is now BiS, this period is always short lived, and always at the end of relevant content (ie; main coil iterations)
4. There are comparable alternatives readily and easily available

The relic quest is the one long term goal in the game that is solo oriented (ie; not requiring a static team to fulfill). Without it, I really wouldn't have much left to do in the game when my coil static is not meeting, that isn't leveling crafting/gathering.
