Circulators and the Unlimited update

If you have at least 1 S rank Inner Ability before the patch that changes it to Ability hits, you better make sure you have 3 Inner Abilities you want. Because after, your Ability will be Legendary rank and you can only use Cash Shop circulators on it (regular circulators only go up to Unique).

So theoretically if one had a lot of NX, you could try getting 3 S lines and wait for the patch and get 3 Legendary lines to cube?
