Another thing to think about is that Noct stance has almost always had a trade-off with its buffs while Diur stance barely had any and has only gotten straight buffs. Granted they had to with some of the shield percentages but still something to think about. Noct lost the regen but the changes to Celestial Opp, to aspected Helios and Collective with only staright buffs to Diurnal and trade offs with Noct hasn't really increased the competitiveness of Noct sect vs Sch. SO I wouldn't be surprised if we got another "adjustment" to Noct sect in 5.15 or 5.2.
