Its the reward. Im a casual player who has the time to spend on grinding a relic weapon. However, after looking at the stats on my NIN weapon, I was heartbroken. I wasted my zeta for a piece of gear that is worse than the standard esoteric weapon stat-wise? If I am going to do a grind such as this, make the reward something worth getting. Ninja's got the worse of this in the new Anima weapons, but other classes were also shafted. Its simply not worth doing the quest for a glamour when I could throw my self at AS4 for the next 2 months and probably come out with a better weapon.
