Honestly, I don't mind the FOMO aspect that much, we've had FOMOsmetics before.
But what does this change solve exactly? The main issue I've seen people complain about is the pack structure: The inability to purchase the individual packs (skin+cosmetics for each frame) and the addition of the Aya which inflates the value of the pack without adding actual value for many people who already got all of Vazria's offerings they cared about all mean that, unless you love both frames and have stuff you want to buy from Vazria, the pack is super expensive for very little useful stuff and a bunch of useless bloat. And your solution is to just... makes the bloat more valuable?
It's like re-painting an ugly old statue that blocks the road without movining it to the side. Sure, it may not be as much of an eyesoar, but the main issue was that it blocked the road!
