The old Astro was perfect. Why even needed to bother something that perfect?... Story matched to it, royal road was easy and understandable in every way and it was the best thing in the whole game. Combining the cards into greater effects was the real control over fate as a "fortuneteller" style of story matched to it perfectly. Every card had its uses even if just a filler pulling a greater crit or aoe crit buff or simply just helping out the other heal with mp regen or help survive a whole aoe mechanic of bosses through aoe Bole (dmg reduction buff was back in that time) for whole group. Its ways of use was endless. Yes, needed to feel the character to use it cause you needed creativity for it. Even if you pulled a card that had no use in the moment, you could keep it for later use or royal road it for more effects. It was so perfect.

Now cards and the whole card system is simply meaningless. Cards have no effects, have no uses. Gives dmg... oh my... ah wait! All gives only dmg and nothing useful. No need to rework astrogian. Need simply restore it, nothing more. Only one change would afect the old astro. The overall remake that every class now use only MP, even the Disciple of War classes. But that is easily solvable by makeing The Spire card gives MP instead of TP like in stormblood. And like this, you still only have 2 card what do the same effect, not 6...
And astro become useful again. Thousands of player gived up healing cause of the broke of asto.

Btw, i never understanded why need to try to upgrade what is perfect already...
