It's not eureka so that is a big plus for it. The story and solo instance/duty was interesting. The biggest downside it that it was a bit short.
They could have added a few dungeons in between (similar to the 2.0 relic quest) to pad the content, at least for the first weapon.
If they wanted to make it easy to get multiple weapons it's fine to keep the current scheme (ie just tomestones) but the acquisition of the first one should have had some extra busywork.
