NO, starting from how server works, how dull the healing system is and how flat when it comes to optimization is making players think less about when to use some tools and limiting mobility on unnecesary ways.
I'm going to talk about the Sch's ideas as its the job I play the most:
Others have mentioned this but this change would make BLM/SMN a must as otherwise too much damage would be lost as well as it doesn't enhance Sch's gameplay since Ruin 2 is a weaving/movement tool and it purpose doesn't change.Change ruin 2 to have added debuff on target to take 10% more damage from casters dots. Last 12 seconds
This is just awful you remove one of the instant cast of a job that needs a lot of instant cast (Fairy and Aetherflow oGCDs) and on top of that makes it an oGCD meaning that the need of instant cast is even worse, not only that but also remove the dot which is core for Sch in order to optimize, this change not only would Sch feel worse but also having less depth.Remove Corruption Mastery II. Change Biolysis to Ogcd, add recast of 60 seconds
Congratulations! You just have killed succor. You're telling me that you're gonna make a GCD AoE that heals 600 potency in total +10% damage mitigation for 400mp and you think a heal that has 405 potency in total for 1100mp would remain viable outside the most niche of uses (a.k.a TEA-like bursts in damage), succor is already a skill that good sch don't use that much don't make it even worse, also casting bubbles feels awkward and sounds like something that would delay GCDs.Change Sacred Soil to gcd no recast timer no aether cost. 400 mp
Same thing as earlier but now you have to compare 600 potency burst oGCD vs 405 potency burst, also that much healing on a burst with a cd of 30s would be pretty OP as SB showed and on top of that now we have access to recitation.Change Indomitability to gcd pot 600.
This is actually something Sch we've been asking for a long timehange Galvanize buff to take damage after Catalyze buff.
This sounds pretty weird, you limit aetherflow on single target to lustrate spam (Which has the same potency of Indom...) and not only that but make a heal that is straight up better than adlo (800 vs 675) even when spammed (400vs 300) only change would be crtidlo but no Sch is gonna use recitation on Adlo/Excog if they are gcds, especially when indom is as good as your best ST aetherflow oGCD.Change Excogitation to gcd. If under 50% on cast no change, if above 3 charges on target each heal for 400 pot, on expires heals 400 pot.
Combos on a healer would be something that would have to change in order to work, you can't have the 15s timer to break the combo on a job that if shit hits the fan has to spend more time using gcds for other things especially when you focus on giving GCD heals instead of oGCDs.Change broil, broil 2 into a combo maybe add a broil 3 for 80+
To be honest overall I think those changes are made from someone that does not understand how triage works or what the oporutnity cost is so I'd suggest to look and learn about that and watch what you are proposing again
