Well I hope you enjoy your white mage with card vfx, and I hope you realize fast that it's nothing like stormblood cards.
Also as a 'parser', jobs with RNG are way more fun than jobs that aren't. If AST has no RNG, the only thing that'll determine my parse is crit RNG and keeping my gcd rolling, along with killtime. With EW AST, it was my own skill and reactions on top of those things, meaning I wasn't just spamming pulls hoping I had a sufficient amount of critical hits and lord draws, it could also offset the RNG with good dps card placement and proper tracking of burst timings and effective DPS under a card. AST was complicated in EW, and anyone who says otherwise just didn't even give optimizing it a try. They just saw the surface level 'card do same thing' and gave zero shits about anything else. It wasn't a fuckin non-standard BLM level puzzle box rotation that needed a spreadsheet to figure out how to squeeze out a 20 potency gain, sure, but it required you to think, and think fast. The difference between a good AST and a bad AST was night and day, and the amount of damage that good card placement actually accounted for wasn't nothing. And fuck, y'know what, even if the damage increase cards gave wasn't that big... at least it would be something. At least there would be something to work towards. Bc right now I see AST being mildly amusing in week 1 prog and completely lifeless and dull for the rest of the tier, whereas before I at least still had card RNG to keep me on my toes and make pulls feel different. Now I'd just be begging for someone to fuck up so I can briefly feel something again. And that's a general healer sentiment.
Every time I think of 'oh but the parsers wanted the job to be boring' I think of this video, and specifically this timestamp. Anyone struggling to understand my view should watch it. I don't want AST to be "meta". I don't want it to be "consistent DPS". I want it to be engaging, and fast, and fun. Let white mage exist for the one button rotation fans, I liked having something, ANYTHING to do beyond occasionally throw out my ogcd heals/mit and press malefic.
