I thought chopping up posts was just attention seeking?
Ad hominem aside -
Could those skills use a rework, sure. Most black mages would like to see them made useful, myself included, but they do not NEED reworked. BLM is just fine where it is. And they definitely don't need to be movement based or part of the main rotation, we already have a good rotation and good movement for a job that's meant to stand still.
Once again, part of knowing the fight. However, swiftcast and triplecast are very easy to use. When progging, you need to hold them a bit and use them as necessary, and as you progress further you will know when and how to use them best for DPS and movement. Just like Dragoon with Geirskogul, popping life of the dragon right as an AoE comes out means potentailly losing a Nastrond, or Monk with Tornado Kick, potentially not having GL3 for a DPS check. EVERY job needs to know the fight to do peak DPS, and good black mages make it work.
Macros. I have AM macro'd to allow me to get out of danger in nearly every situation with little to no issue. You can also just use <mo> and select a healer, because a healer will always be in safe spot (typically). And if you're in static, you can choose a specific person, bard perhaps, to teleport to as they are very mobile. Many options, not that hard.
It works BEST when you know the fight, but a good black mage will make do with whatever they need. And she said black mage isn't punishing for mistakes because the rotation is VERY easy to get back to. Unless you fuck up twice and lose Enochian twice within ~17s, you will never really be out of your rotation except maybe losing an almost-finished foul. Dragoon, should you happen to lose BotD at a bad time, could lose potentially 60s of rotation build up. Summoner could lose nearly 2 minutes of work. There are less punishing jobs like Red Mage, but certainly more punishing ones as well. You need to know the JOB to be good, knowing the fight just allows to be great.
And she's mostly right here. You still need to keep an eye on the timer in the event of downtime or an incoming boss jump, but for the most part you will not be looking at the timer. I only ever look at my own gauge when an AoE or something is going out. And most jobs can ignore the gauge for the most part as it's just part of the rotation, unless they're moving or during downtime.
EDIT: you edited another point in right after I posted this. To that point, as we have all said, there are issues. Like the useless spells. But BLM is in a great spot for DPS (thought i could agree to a ~2% further increase to push us out ahead of Summoner and their rDPS) and for it's rotation. The rotation flows almost perfectly. Foul almost always lands during your UI rotation, 6 F4s is easy to attain, plenty of time to do 3x F4 and 1x F1. Black Mage doesn't NEED anything, but it could use a few QoL changes. Like the ones coming next week. The problem everyone has with you, is that you want the entire job scrapped and rebuilt, and nobody else wants that.
