In what realm is the ability to undo whatever's inconvenient to you not a buff? Now, you do realize the playerbase has quite a bit of sway when it comes to how Jobs are changed, right? Asts have been screaming for changes in the most surreal areas, like this post for example, and the developers go along with it, and then we see a sharp decline in healer variety. Because this one thing is inconvenient to you, you need to go out and make a forum post and hunt for people that are on your side because you need the validation.

I've been just fine with the changes. The problem is, the playerbase that likes to whine is much louder than the playerbase that's satisfied, because people don't get on the forums to tell the devs they're just fine with the changes.

What you are asking for is an RNG system, without consequence, that allows the player to draw basically whatever they like (with all these Draw skills), and throw away whatever they like. An RNG system where the results are manipulated in order to obtain the ideal outcome every time, and there's never a time where cards are less than welcome.
