I've talked about this in an earlier post though... SMN did in fact get a buff this patch right along with blm. Bio is going to cost less mp (really good for turn 8 or any other fight where you want to spread your dot love around like ifrit ex). SMN maintains the same advantages they once had in the past.
For example a smn in turn 6 is not heavily punished by vines and is the only dps that keeps most of their damage going through the entirety of blighted bouquet, simply dot the bee, and refresh any dots you can on the boss and bam huge advantage. With the new garuda instant cast aoe you can use that to get some bonus damage on brambles under raffy.
In turn 7 smn can kite without losing much dps while hitting literally everything in the arena with dots (remember the bio 2 mp reduction?)
Turn 8 is a single target dps fest which you still have the advantage on especially since bio 2 has had its mp reduced, ifrit has gotten buffed (since people like to refer to garuda as an mp saver in this fight) and you probably can work shadowflare mia 2 in your rotation in this fight more often now. SMN much like bard can do every mechanic in the fight while losing little dps in the process, it just requires planning.
Turn 9 a smn isnt punished at all, I'd even call them king in this fight. You are not punished by positionals in the fire/ice/lightning phase. you can multi dot all 3 of the golems for huge damage in the golem phase, you can maintain damage while running and running away with meteors. On top of this you provide an extra body for thermonic beam, have a raise cause shit happens sometimes, have an improved virus and can cast eye for an eye more often. and the dragons practically beg for bane.
In levi you can double up your damage by maintaining dots on the head and tail + as many as the spumes as you can possibly juggle, smn is undisputed king in this fight.
Moogle they do well too, unfortunately dotting like you do in moogle does require your pt and yourself to actually pay attention.
The only real weakness smn had was endurance fights and frankly this patch helped you out there. So really you benefited. a good blm cannot keep up with a good smn/mnk/drg in this current patch.
For the record I'm an 110 blm with an i115 weapon and I'm an i110 smn with an i115 weapon. I play and enjoy both depending on my mood. I cleared coil first as a blm cause I was stubborn about it and then cleared it on smn.
SMN is a high dps, high utility job that isnt punished by mechanics and in many cases excel at performing them. With the buff blm will pull ahead in certain fights, but it should be that way since previously it was completely unbalanced. The only big kick in the nuts that smn gets is when they die with aetherflow recently used.
