I play a lot of SMN and don't really favor either suggestion lol

To me SMN is about making those 30 second recasts count and then they become amazing when you unleash one hours. Our wards are very lacking at the moment though. Phalanx and stoneskin effects super weak compared to player version using accession. Evasion and accuracy buffs/debuffs are not worth using compared to even what some DD can do, including shiva's high level pact for debuffing evasion. Compare Distract III of rdm to the -25 evasion Shiva gives or Feint of a THF, which maybe you could come up with some argument for. But considering you can sub rdm and give -35 evasion from tier I distract and a high level pact of Shiva gives -25 evasion seems really off to me.
There's a lot more so I am hoping the update will really help us. In fact if I sub rdm in the 30 seconds it takes to cast one blood pact ward I can have better phalanx, better stoneskin, better evasion down, better shell effect than shining ruby and depending on my def rating better protect. Having more power from subjob vs 30 second recast pacts is not good for SMN at all. While we do have some powerful wards, like Earthen Armor, and Hastega II, they represent when wards do what they are supposed to do... be powerful party wide buffs or debuffs on the mob with long duration and long recasts. Back in the day it was awesome to see SMN keep up haste 1 and aerial armor on an entire party and keep you safe with stone skin, phalanx effect etc. Now I feel like why do I have these wards at all if /rdm subjob beats them.
Favor is nice but you are limited in where your pet can be and what pet you can have out. If the mob isn't weak to ice, you get to stand there and do nothing the entire fight after you cast a few wards if you are asked to give MAB to a mage party. But why would they ask you when COR is far easier to gear as a support up to speed and there's a lot more of them and they can give magic acc and mab at the same time? Dream shroud depending on time of day gives you some edge but not enough to make up for an entire other roll. You could conflag strike and impact. But the mobs don't tell you when debuffs wear to reapply and while you reapply poof goes the favor and has to rebuild. SMN can do a lot but they don't let us make a choice between support and do damage and due to how favor works unless you're very luck on the mobs weaknesses you'll never really be doing both, and if you are lucky enough to have them be both, you have to make them miss favor sometimes to reapply debuffs or do damage if the mob is too far away. Even if you stack all our outdated buffs at one time, and do favor, people will prefer COR every time. And COR isn't even strictly a support it can deal heavy damage and while I agree SMN can do great damage if you unleash your one hours, the rest the time it can't keep up to other mages simply due to recast.
Unlike BRD, GEO and BLU we also can't cap magical haste so at most we over load with indi-haste or save a bard one song. BLU it can work but if their stacking haste is dispelled it's welp. Basically there's no role SMN fill well, and if you try to do both support and damage, you miss out on avatars favor nearly totally and our old wards a lot of them sub rdm is better than them. So as it stands now people only respect SMN for three things: 1 hour ability, which just makes it sort of like a BST that has better magic burst options, and no physical AoE and Mewing lullaby on a few hard nms to lock out TP moves, which with enough support subbing summoner a full smn isn't needed then either. So that leaves... 1 hour and flaming crush on weak mobs as the third. Flaming crush doesn't scale well at all though so around t1 reisenjima it's not really that useful at all and you start using things like volt strike instead. I thought SE was gonna try to fix SMN from being just a 1 hour tool. Alexander was weakened a lot, and now we can do awesome damage every hour, but we still just slaves to that 1 hour timer. SMN needs to be useful enough while that's down to get party invites if you are seriously considering balancing it. I should mention too, if people screw up skillchains or bubbles when you 1 hour, or a badly times amnesia or petrify goes off on the avatar or it's killed mid 1 hour, it becomes pretty much a useless strategy so it has downsides too. I like the idea of SMN being able to unleash the full potential of an avatar every hour. But it being the main thing it's used for as a job is stale and resetting 1 hours every time you wanna do something hard that sch blm and geo can do w/o 1 hours gets very old very fast. I realize people are tired of hearing about SMN rants probably from me and a few others in particular, but these are what are actually facing SMN as a job right now if you look at endgame with endgame event LS, and like it or not people play to endgame strats because that's where they want to eventually belong so if you can't fix it there you can't fix it anywhere else.
