To make it short, I was just tired of people laughing at SCH just giving quick statements like "Lol SCH sucks" "no wonder you lost, you had an SCH in your team, how could he thinks he could handle the fight" (not exact real quotes, it's extremely close to that, coming from some top 10 players on Chaos just laughing at how obvious SCH is bad).
So I asked some people to have their opinion on why they say it sucks.
Overall I don't want to give names or channel discord to don't discredit people in the eyes of others, I accept the risk for me, but not for the other ones who didn't want to express their opinion here, and it's just opinions given to me when I asked what was that terrible about them, they were not like stating they were almighty omniscient on the topic (some were top 50 and one only played it when he was still Bronze but still wanted to tell me why he stoped playing it). On top of it, I mixed several people thinkings, also mines, and I don't want anyone to believe one of them said everything I mixed together.
So I'm glad you believe they actually can be good (more made for premades then?), and having your opinion about why they are enough the way they are.
Just in case, I was not talking about FL, I'm mainly interested in The Feast.
For Aura Blast, I'm not saying its main purpose is to provide Faery Gauge (btw, I wrote Faery Gauge sometimes, Seraphic bar another time, dunno why, but I'm aware it's Faery gauge overall), but filling it by 10 per target makes it not something we can ignore at the pace the game goes in Feast making it hard for SCH to have time to attack and fill that bar, it's still a huge part of the skill, even if the Knockback is the primary part of the skill.
(I didn't understand the frog part when you said "Using Aura Blast for Gauge is concern frog").
I didn't mean Excog was specialy comparable to Solace, but SCH has way more oGCD than the others (on top of charges). So as it's an overall kit, it's hard to compare every single skills equally. 3k heal + 3k shield is maybe obviously too high, but I still feel 3k every 45sec looks a bit disappointing.
If I mix all oGCD of WHM on 30sec, we have 3 Afflatus Solace, 2 Tetragram, 1 Assize (+ could be buffed by 20% by Temperance(60sec CD)) --> 7k heal per Solace, 4k per Tetragram, 2k(AoE) per Assize --> 21k + 8k + 2k = 31k total heal (of course, the Solace regen doesn't stack).
Meanwhile, SCH on 30sec has 2 Lustrate, 1 Indomitability and let's say they have 1 Excog. even if the CD is 45 CD (+ could be buffed by Focalization) --> 3k per Lustrate, 1.5k (AoE) per Indom, 3k per Excog. --> 10.5k total heal. (I didn't coun't the Seraphin of course, but it's not something that can be count on a reliable way overall.
I've tested Seraphin directly, it's really disappointing.
Using 50 or 60 Faery gauge : 3 Heals (6000 Heal + 6000 Shield).
Using 70 or 80 Faery gauge : 4 Heals (8000 Heal + 8000 Shield).
Using 90 or 100 Faery gauge : 5 Heals (10000 Heal + 10000 Shield). (we can see the Fairy cast the 6th heal but it doesn't come).
Logically, at 100, we could expect to at least do the double of 50, so 6 heals. And being 22 sec, we could expect even a 7th healing skill because it's every 3sec and 7 x 3sec = 21sec (and it's 22sec duration at 100 Faery gauge used).
On top of it, we can see we waste 10 Faery Gauge at 60, 80 and 100 Faery Gauge used.
Even if I add the 5 Seraphic Veils to the total of "heal in 30sec" from oGCD (it's wrong to call it that way but I hope you get the idea being more like "what healing value oGCD comes back in 30sec"), it makes it being 31k for the WHM and 30.5k for the SCH (and it's way less reliable as the AI of the Fairy is not great and it needs the Faery Gauge to be maxed).
One great thing about the SCH is the shield part of Adloquium and Seraphic Veil counters lifesteal mechanics (Bloodbath and Drain), and can prevent a bit of overheal if used too early. On top of Biolysis lowering healing by 20%, it seems pretty great to lower opponent survivability.
On the other hand, they lack a lot of offensive abilities compared to the 2 others (maybe Seraphin is here to allow them to more use their basic dmg skill to heal better after).
