That is fair and fine, but doesn't change the fact that Ast potencies are flat out inferior to Whm and there is, apart from having more fun to play the class, literally no reason to bring Ast instead of Whm.
As I said it doesn't matter much if you are just playing casually, but for more competetive gameplay this is an actual issue.
I do agree that the idea of Neutral Sect is really good and an obv choice for Ast, but I really dislike the duration and CD.
You get: 20s of both sects on your aspected Skills every 2min, but Asts whole skillset prevents you from spamming GCD heals. So why the long duration?! + You obv don't want to spam asp. Helios bc you why would you want to overwrite the buffed HoT it applies instead of letting it work on its own?
The skill could be much better with a much shorter duration (say 10s, more than enough for both 1 asp. Helios and 2 asp. Benefic) and therefore a shorter CD. But I guess they can't do this because all healers need to have a strong 2min skill that lasts 20s.

It does work well for Sch and Whm, bc the Seraph is just a buffed version of your regular fairy and Temperance boosts your Lily heals which you mainly use for healing anyways, but the concept is just lackluster for Ast and all their oGCD tools.
