And who's to say that Nexon can't change how the skill point progression works for Booster (or any other skill for that matter)?

With the way skill points work anyway (where every job gets to max just about every skill at each advancement, with zero variations) having Booster at 1 point mastery level vs. 10 points is going to make jack all difference.

Rather than get caught up in the technicalities, look at the substance of the changes.

I completely agree with your points. I don't see Nexon changing it any time soon, though, if ever.
