Unless we see a U-turn on how the devs view how healers should be any new idea will be forced into their current vision. Since this is how they intend healers to be, they can be wrong but they would have to acknowledge that they are which they haven't not regards to healers anyway.
Remember the state 5.0 ast and sch were they honestly thought it was perfectly fine same with 4.0 lily system. Then look at how healers have 'progressed' since HW, SB more heals added gauges 1 being entirely pointless until ShB and loss of dps tools, ShB even more heals more loss of dps tools but gauges have uses but most hated iteration of all 3 healers (most people never hated whm it was just under performing to its competition now I actually see people hate it due to the downtime issue plaguing all 3 healers).
With the devs mindset since midway through HW (time they probably thinking of job changes for SB) I cannot see chemist having its iconic mix not be incredibly watered down.
If Chemist was released for HW, sure I could've seen it happening.
If Chemist was released for SB, I could've seen that happening too.
If Chemist was released for ShB, before press release yep same as above,after press release nope.
Can I see Chemist released for 6.0, Nope. Not until the devs show a massive change in their viewpoint and design process.
