In what way is my suggestion more conditional exactly? In SB, you used Cure 2 to generate a lily and then any 1 oGCD would use all your lilies to reduce its own CD. My suggestion merely requires Divine Benison to expire in some fashion to reduce the CD of all our oGCDs. The difference between the 2 is that you aren't blowing a GCD for cure 2, you aren't blowing all your lilies just for a single oGCD CD reduction and the trap that is freecure is removed. I personally liked the CD reduction SB gave but felt it was poorly implemented since it was reliant on Cure 2 to have any effect at all. I'm merely suggesting that there be more interplay with Divine Benison because as it is, its just a shield we weave whenever possible and that's it.
The Lilybell suggestion is to try and make the skill into something that is actually useful to use while also keeping the Lily system relevant in EW. With a 1.5 second cast time, the opportunities for us to weave in Lily abilities vs just casting Glare will dramatically be reduced and while we'll still periodically need to use a Rapture/Solace, there will be instances where we can stockpile 3 lilies, if for no other reason than a long transition period that gives us nothing to do but sit there and there was plenty of those in ShB that I can't help but feel will also happen in EW. Even if Lilybell cost 3, or even just 2, Lilies, it would either make it a DPS gain for WHM or a much smaller DPS loss than what the Lily system will currently be going into EW. If we have 0 Blood Gauge, then using a single Lily skill to get Misery is a DPS gain for WHM of 280 potency, whereas if there's 1 gauge, the DPS loss would be a mere 30 potency since we'd only be using 3 GCDs for Misery vs the 3 glare casts during the same time frame of GCDs (this is assuming that Misery remains 900 potency and Glare 3 is 310 potency). Either or, its a much more reasonable change than what Lilybell is currently looking to be with a 3 minute CD and no interaction with the Lily system at all.
The thought process here is that, Selene in her current form is merely a glamour piece; Doing the exact same thing as Eos really just makes either or an aesthetic choice and that's really it. Restoring her old abilities would at least make it so that there's an actual choice in which fairy to use again and while she only offers niche utility, its still utility none the less. As for Enhanced Aetherflow, while not addressing SCH's problems, it does create more interplay with the toolkit as a whole, which is what I'm aiming to do. Death is equally punishing for all roles since you loss all progress you've made with your gauge to start with and any plans you may have had have already been derailed by the death, so I don't really see it as exasperating that problem any more than it already is.
