I do raid. I raid 1 day a week now because even my casual raid group cleared everything in just a few weeks. The rest of the week I hang out with my dog and go hiking after work or level my alt casually. /shrug So I'd have to say you are wrong on that front. I have a full time job already that is very demanding.
Not only can sch 'get things done and progress' they are still considered the go-to healer for raids for both their healing ability and dps ability. You are acting like sch is the worst healer right now when in reality we are arguably the best. Healers are very balanced right now.. but still sch/ast is the best pair for healing and dps. We saw some initial whm/noct groups but in raiding we still see far more groups running sch over noct because its just overall better. In more casual content, sch still excels. The only reason the number of skills is important to me is because it makes my UI very awkward.
I don't know what doesn't mesh to you about sch. You shield people. You dps. Mechanics eat the shields. You re-shield them, you dps, and if the shield isn't enough you use an instant (lustrate, excog, indom) to heal. And you have other things for emergency healing (CDs, SS, ET, dissipation). Sch doesn't have much hard casting to do these days. And the shielding + free fairy healing has amazing synergy with the focus on dps in this game. You can get a ton of dps out while your shields break or your fairy heals.
I'm going to try and wade through the typing errors here.... Things like heals producing(?) stronger heals. What do you mean by this? Whm doesn't do this. Casing abilities builds stacks for better abilities? I think i get maybe 1 lilly per encounter on whm. The lilly system is still trash. It's garbage and needs a complete re-work. You are trying to say that whm got some cool new things in the expac, but in reality the playerbase hates those things you are referring and it's a bad system. So I totally disagree. I don't think I cast a single cure or cure 2 spell in all of exdeath or neoexdeath. I can pull up the log. Their idea and design for this system was just bad. We definitely don't want a similar system on sch. Also you are off about Ast as well. No card left "unwasted"? How is that true? most of the cards are still junk and we are still waiting on balance. They made spear a bit more viable... so now you get balance and spear, and the rest of them are extremely niche. Ast cards have the same problem they had before, except now you can do shit with them through Lady/Lord. Even adding that system was SE pseudo-acknowledging that many of the cards are going to the trash bin. I think you might mostly play sch from your character sheet. You may want to play the other healer jobs at 70 to see they have thier own issues. I'm not saying that is a reason not to make changed.. but I think you are basically finding fault in a lot of skills where there isn't much. I will say if you play more casually, a lot of skills on sch are going to be wasted. Sch is really designed for savage and that's where their kit feels really impactful and fun. As far as place in the game and the meta I'd still say whm is in the worst spot with diurnal ast taking so much of their identity. I've posted about this before, but this thread is about sch. I'm basically saying, I think you are trying to find things to complain about on sch. Sch now is really not much different at all from sch in HW. It's just that the other healers are closer in balance now so sch is no longer undisputed king of the entire universe and I think that makes scholar fanatics a bit salty.
