The logs for SMN's rdps only gets lower the worse you go based on initial clears:

It's important to note that these are week 1 clears and so a small swing in dps will result in large percentile differences (and its why 50th percentile bracket is not a bad choice) - For the most part however, those who are hardcore savage raiders clear the fights in week 1 and it is telling that SMN is pretty low at all percentiles on the final fight. Summoner is bottom 3 regardless of which percentile you pick.
Infact, 30th percentile and below it is the worst job for rdps at this time. There are a multitude of reasons for this and these stats are not necessarily a true depiction of how things stand as some jobs may have had gear prioritized more than others and there is a lot of luck associated who won gear on earlier floors which could bring the average up. What is telling is that RDM is higher at all percentiles. RDM clearly does not need nerfs however (if anything, it deserves more buffs). It's just telling how weak SMN is at this current time due to the current design iteration of the job and its reduced flexibility, rigid mobility timings, fester ruins and how much downtime can punish you.
The job is in a bad spot and I would very much like our cycle based on Aetherflow again as it was a great system and very underappreciated. You did not need the Aetherflow lockouts in trance either as you could simply have DWT or FBT activatable as soon as you refreshed Aetherflow meaning you could use said stacks inside DWT/FBT. Further, to distinguish DWT/FBT setup in this way, you could rename the Aetherflow mechanic to Energy Drain which makes DWT activatable on refresh and Energy Drain upgrades to Energy Siphon after you have already used Energy Drain and it is on cooldown or DWT ending which signifies that the next trance available will be FBT and so on. It would have been a very nice and straight forward improvement on the old 4.1 system. Instead we have this more rigid system which has many faults.
