i remember when f213 was free on everyone..... until i started fighting @Orochi and i stopped using it forever r.i.p. the move that got you +10 frame advantage.Using F21 let's you hit confirm into both LK and SP. MB SP trait combos get about 5-6% extra damage and you can get better positioning by choosing to switch sides by using regular MB SP.
I use F21 a lot because of the options it gives me and my opponents aren't always quick to punish me for it. If I realize they are looking out for it and punish it every time, I'll refrain from using F21 as much.
