As a Scholar main; if you want to genuinely improve, you should look at your logs because there's a lot of fundamentals you are lacking on a basic level. Ultimate Legends screwing up mechanics aren't the reason for your logs looking the way they do - while a healer's parse is affected by the quality of the groups they run with, when everyone else is doing so much better than you, the group isn't the problem.
You'll probably take this as an attack, but it's genuinely not, I just really like talking about Scholar (which is why like 95% of my posts are specifically about it) - you don't have to listen to this advice at all but if you do your gameplay will improve and you will be a much better Scholar for it.
You don't use Ruin II at all - while it is optimal to never use it, using Ruin II is better than just not casting at all or canceling Broil IV casts to move. If you need to move more than slidecasting and your weave window allow, use Ruin II. If you need to weave more than 1 oGCD, use Ruin II (not optimal or recommended generally, but if you're having to focus on healing, do it)- you have weave issues where you're using 2-3 oGCD heals between Broil casts. You can also refresh Biolysis at 15s or lower if you need to move as well, as 15s is where its worth more than a Broil IV cast potency wise. Obviously you want the full amount (refreshing Bio at 3s) for the full 700 potency, but if you need to move/weave 2 heals and you can use Bio for that at 15s or lower, it's not a DPS loss like Ruin II is. In a way, Ruin II makes Scholar the most mobile of the healers in unoptimized environments as you're always going to be able to be doing damage while handling mechanics/moving, and the 75 potency loss per Ruin II over Broil IV is much better than the full 295 loss of not casting anything at all, so make sure you're using it over nothing at all.
You have low uptime on Biolysis; you need to make sure you're constantly keeping uptime on your DoT, a good part of your damage comes from it and the more you keep your DoT ticking the less over all damage loss using GCD heals like Succor and Adloquium are over the course of the fight.
You're letting Aetherflow drift over the course of the fight, resulting in lost healing that you're having to cover with Succor/Adlo and lost damage from not using Energy Drain, which you didn't use at all during the fight. It's easier to treat Energy Drain as a stack dump rather than a purely offensive tool; get into the habit of using Aetherflow on cooldown and if you have any stacks before it's about to be off CD again, use Energy Drain to dump them. Every Succor you used could've been covered by Indomitability or Sacred Soil; etc. It is less of a DPS loss to use Aetherflow heals first, so ensuring that Aetherflow doesn't drift is the best way to make sure you can heal as much as possible before dipping into GCD heals. Keeping Aetherflow on CD is basically the most key mechanic of Scholar; it is central to your MP economy and how you heal, so be sure to focus on making sure it drifts as little as possible.
You're also not using Recitation, Seraph or Expedient nearly enough; Recitation is 90s and Seraph and Expedient are 120s, you should use them fairly liberally, Recitation especially should be used to cover healing as much as possible, Recit Indom or Excog are cracked and heal a lot. I know it can feel like you need to save Seraph/Expedient for when they would work best (I find myself doing this a lot) but it's better to use them a lot and then hone in on the best usage per fight rather than just saving them and only getting 1 use per fight. Always aim to get 2 uses of Consolation from every Summon Seraph; I like to preshield large raidwides with the first, and then heal up the damage with the second Consolation. There's no reason to ever not use both as they will both be available the next time you can Summon Seraph. Expedient sometimes feels like you should use it for the sprint and so a lot of Scholars hold it in anticipation for a mechanic that might be useful, but it's also 20s of 10% mitigation, so using it to mitigate more than using it for the sprint can give you the most mileage out of it.
Also Whispering Dawn should be used as much as possible, the regen is great and it and Fey blessing should always be your bread and butter heals on Scholar first before dipping into Aetherflow. Your healing priority on Scholar is basically Protraction>Faerie Healers>Aetherflow Heals>GCD heals so try to minimize your GCDs as much as possible.
Anyways I won't derail this thread further, but if you want to talk about how to get better at Scholar or healers in general feel free to make a thread on the healer forum and myself and many healers who are better than I would love to help.
