I m ok with any grind, as long it doesnt have a RNG-factor (and doesnt involve FATE grinding). The third step was extreme and the tomestone-farm-step was not that bad. The thing was, that you have different ways to get your hands on Crystal Sand, but only one way to get Umbrite.

But I still hate the very first step of this questline! Its extremely annoying to grind FATEs for hours and just get only 1 crystal, while other people clear all zones in the same time. THAT IS NOT FAIR!

Farm lights by doing dungeons and stuff? I m ok with that. As long they dont put any RNG into it (like random drops for dungeons or ATMA farming BS).
