Because again, the difference between different cards is tiny, and every card does something immediately useful, ie; increase dps. Oh, and I don't like minor arcana either, fyi, for the same reason I don't like stormblood cards. They might have worked back in stormblood, with stormblood fight and job design, but if you try and transplant stormblood AST into modern ff14 it'll feel like shit to play.If you think old AST was extreme frustrating to optimise, how is current AST any different? Your contribution depends entirely on whether or not your party crits under your buffs and Lord of Crowns is still RNG.
Having RNG damage is fine. Every class has that just by the nature of how crit, damage variance, and/or kit elements that add it. The thing that old stormblood had that would be an issue now is the issue with minor arcana amplified to the entire class design. Cards that do damage always do something. More damage. But cards that provide mit, healing, mana regen, etc that cannot be predicted or consistently placed into a mit/heal plan become completely useless. You can undraw them, use them when you get them, wait until a situation that requires mit and throw it out as like a bonus... the effect is still the same. You have to plan and play as if you never draw these cards, which makes drawing them pointless. Or you can turn your entire healing rotation into a flowchart, which I did when I did TEA with minor arcana, which I hardly noticed half the time.
If you're given tools to manipulate RNG and draw the card you want what is the point of having draws in the first place?
Geez, tell me you don't play current AST without telling me you don't play current AST. For starters, you play three cards in a burst window. Do you see the issue? What if you draw 3 melee cards? Or if you draw 2 ranged cards and 1 melee card and are forced to card something like a dancer instead of a higher dps melee? Second... It's not nearly as frustrating to optimize bc you don't lose or gain anything but damage. It's JUST your dps output that changes. And you're always playing cards that do damage, it's just a matter of how much. Whereas with old cards, you'd be drawing cards that are completely irrelevant 4/6 times. I'd rather draw a suboptimal dps card than a worthless mit/regen/heal card, bc at least when I play it I actually feel like I'm contributing. There is no 'working around a bad card draw' with StB. You can burn it for royal road, but that doesn't do anything but potentially make the Balance better. And if you don't draw the balance, well you're either just gonna keep burning cards, undrawing them, or wasting them bc you planned your heal/mit plan around NOT having them.AST has always been frustrating to optimise, the only difference now is that you don't have to work around a bad card draw. Astrodyne is worthless and in a log run, you'd always have 2 melee and 2 ranged so you'd never have sub-optimal card plays.
