So I thought this was kind of funny. You can do a near instant over head HD bypass j.A. If you hop j.A like you usually would for the instant overhead and then activate HD a bit later Leona still do the bypass in mid air as opposed to staying on the ground if you activate HD at the same time as j.A. Unfortunately it causes the j.A to come out later than normal so it doesn't work on everyone. Characters that duck low and are narrow like Leona, Ash, King and Yuri can't be hit by it but the bigger characters like Iori, Kyo, Kim, Duo Lon, and Shen can get tagged (haven't tested everyone). The timing's a bit picky but it's another fun little 50/50 you can break out on someone if you're sitting on 4 bars and HD.
