So I have 3 different characters across 3 different datacenters. Back in 2.0 I went summoner. I dabbled a tiny bit in SCH because they shared xp and got to experience cleric stance which I thought was kind of neat. I had to manage when to heal and when to assist with damage with OG Titan EX.
Back in HW I restarted and went WHM. I liked the class so much that when Shadowbringers was about to come out (I missed a good portion of Stormblood) I made another new character to play with friends and went WHM again. I enjoyed Stormblood WHM just like I enjoyed HW WHM.
Then Shadowbringers made healing way, WAY too simple. I thought "No big deal... I guess. I still like the class even if my damage is a 1 button mash. I can at least have fun with the healing aspect, trying to play nice with an AST that went Diurnal or Nocturnal." Endwalker comes out and I still main WHM up to the end. But I realized how little healing I was ACTUALLY doing. 90% of the content (dungeons, trials, raids) didn't really require me to actually focus on healing for a minute. Usually an Assize here, an Asylum there and nearly everybody's topped up. I'm essentially spamming one button with re-applying a DoT every now and again. Then the raid comes out and I'm like "Ok here we go. I know at the very least savage usually has more healing." And it did... very little. I had to worry about an extra lily here or a temperance at a specific spot to keep people alive. I still wasn't really "healing" as a healer.
So I say screw it and go MNK. Have an absolute blast as MNK with how challenging it can be and the fact I'm not spamming one button and actually being aware of certain parts of the fight. Would it be worth re-applying the DoT here? Can I fit in a kick right before the boss goes untargetable? New savage comes out and I decide to give healing another go. Then realize they added bleed DoTs to nearly everything. Surely this time I actually need to do... you know, the class I play?
Nope. Just the same old same old. I'm spamming one button and maybe throwing out a heal. If they don't mitigate properly I actually have to worry about applying heals but I'm still not actually healing for 90% of the fight. So I'm done with healing until there's a rework. I just hate the fact that I selected a class, who's literal role is to heal, and even in savage content I rarely do my job. I'm just a much crappier DPS that has more than one bloodbath or second wind. I don't focus on heals I focus on damage to meet the check. Because that's the way they're all designed. They're not designed to make sure I keep everyone healthy. They're designed to make sure I'm spamming my DPS almost as much as a DPS is.
