I'm not even saying to learn your rotation. As even already pointed out with half of the classes in this game by Rymm, the game actively tells you what combo's with lighting up your buttons.
On your BLM and SMN you're incorrect. Your procs blink to alert you that they were obtained, such as Firestarter, or Ruin IV. Also, I've had my expectations murdered enough to the point where I don't expect the RDM to melee, I don't expect the NIN to use anything but Doton, and I don't expect more than the gecko combo from a SAM (Yes, I don't even expect them to laijutsu anymore) and they still somehow manage to do even less than that.
But since you're mentioning more jobs, here's a question. Bards that never sing. Dragoons that only heavy thrust. Actually dragoon's a funny topic, because in 3.1 I ran into a lot in expert covered in full vit gear.
They're tanking? Well I guess Rymm's main is a Paladin I think.
Also not having that expectation either for buff allignment. Notice how my wishes for someone in 50+ content is to at least be pressing more than 1 button? And I'm saying they somehow still aren't? I'm actually going to focus on the dps factor here, because one of the few reasons I wanted to drop SCH/AST was because of dps not doing anything. You ever see a 45 minute run of Compass? With no wipes mind you. Was almost common if I went healer, and almost always 15-20 minutes when I went BLM. Strange.
You'd also think people would actually want to be done things sooner than later too, actually. While this is a WoW example and not a FFXIV example, a Youtuber (Preach) did a challenge to prove some people wrong, about how pugging is. One thing he noticed was that he didn't realize how little he actually played until he did that, because people were so bad and not wanting to improve, that he would spend an entire day just trying to upgrade his keystone by 1 level.
So that's just an extra note. You get to do more activities if you actually read your abilities and figure out how to play. Guide or no. And honestly if you need a guide to tell you to use fire spells as a BLM, or to use combo lines on a melee, you probably shouldn't be at a high level. The game outright explains this to you. Go make a new character, pick BLM, and don't turn off those little hints they give you. At level 2, they actually explain Astral Fire and Umbral Ice to you. And there are people at 70 who can't even do the thing explained at level 2...
Also here I am making walls of text to a person who I'm thinking doesn't even speak English. Oh well. I don't pay their sub, so I should just carry them because they also clearly pay mine.¯\_(ツ)_/¯
I've been either ignored or verbally harassed for almost exactly the same wording as your examples almost every time. In some cases, even after the dungeon was completed and I left.
Yes, people got that uppity that I asked a BLM to aoe, that they whispered me after the dungeon to tell me nasty slurs that, again, I'd post, but get reported and banned for just stating the words.
