As someone who did Skalla 472 times (I got it in patch 5.2) before I saw ONE aiming top drop (I wasn't losing rolls, it just literally never dropped) please do this. At the very least add it to be purchasable after 99 tokens. After 200 runs, I didn't even want the top anymore I just did it out of sheer spite.

I remember hating Stormblood very intensely and taking a 6 month break which is the longest I've ever been away from this game, and the Skalla top was one of the main reasons why.
