Long time player who mostly does casual open world content. Celestial gear can be pretty fun for open world content, and I like the of having only one set of armour per character. Though I believe the fact that celestial armour has toughness somewhat negates its usefulness in endgame content?
This is mostly on the context of a celestial firebrand.
@asal I can speak from my experience. I made Celestial Ascended gear for my Alac mechanist. It was really just a project for me, was looking for something to do in game. I don't really have much interest in Fractals, but now I'd be ready. I think if your intent behind making cele ascended gear would be to get into fractals, know that cele will likely only get you so far. Higher end groups look for specific stats for the most part.
