More interested in White Mage? No, not really. WHM isn't really super special or interesting. It just makes things easier. Period. It's super straight forward. DS Regen and Medica II, Asylum and the HoTs will typically keep the tanks up enough for you to actually toggle Cleric Stance to DPS. Even if you can't, guess what your co-healer can do while you main heal? You guessed it! DPS! Strong healing Cool Downs? What is that? Lightspeed? While Lightspeed is MUCH better than it used to be, it's only available every 2 minutes and 30 seconds IIRC. While Divine Seal itself is on a minute timer along with lalalala Tetragammaton. Even Asylum and Assize are up before the re-use of Lightspeed. You don't see anything wrong with this do you? The best AST gets is Essential Dignity on 40 recast and it's efficiency lies on the lower the health of a person gets. However, once this is blown and they're thrown back into the red, what are you going to do? Lightspeed? Fair enough. Now Lightspeed and ED are down, tanks are in red again, what's next? Nothing. You spam Benefic 2 for deal life and cry because the potencies are weaker than that of Cure II. (Ideally weaving in the predecessors for procs, but I believe this is just basic knowledge)
Yes, AST has some interesting mechanics with their cards. But time and time again, it falls upon RNG to bless you with the cards that you need to actually promote these "buffs that compare to WHM and SCH". Consistency is key. That's what people seek for in progression. Not RNG. Here's something else to consider...Are you always going to be throwing out Buffed Balance cards to your DPS in progression? No. You might be throwing yourself or your Co-Healer an Ewer for MP management. Or Spire for the DPS. There's these factors you need to consider too and not just the 100% Balance all the time. Stop speaking from a OPTIMAL situation and try and more REALISTIC scenario where you are NOT getting the cards you want all the time. The time you spend throwing cards or using cards for RR preparation, you Co-Healer could be DPSing but they potentially CAN NOT because AST has trouble managing on their own on Raid Wide damage. Single Target? Not so much. But dual damage on tanks? Depends on how much they're taking. But AS2? Possibly manageable, but Synastry isn't always going to be there to help you.
