Masquerade! Paper faces on parade. Masquerade!
So once upon a time in the recent past you deliberately went out of your way and made yourselves clear that with Alchemy you could not change the formula requirements for anything because users had already begun to use the feature and complete the formulas to level up. Recently there was a thread here in SF stating that the Formula 3: Sundae's Treat used a limited edition '05 Easter holiday item the Bunny Tail and demanded that be removed. Now, instead of a Bunny Tail sits the requirement of one Bento Bunny, an item that is still limited in nature and even more expensive than the last.
Seriously, do not tell us one thing, do the exact opposite, and expect us to take everything like it is all full of rainbows and bunnies and cotton candy. You just proved, AGAIN, you can change something even though others might have dove into it already.
Hide your face so the world will never find you.
