3rd Strike legend VS_Ino made a great video demonstration recently on a powerful defensive tech in Street Fighter V: the Backdash-Tech option select.
The OS does exactly what it sounds like: with proper timing in meaty situations you can block, backdash, or break throws. Complete with (often times humorous) English subtitles, Ino demonstrates the power of this OS versus meaties, shimmies, and even as setups in minor frame disadvantage situations. The OS is not foolproof, of course: it still loses to meaty lows, and it’s still got all the weaknesses a backdash normally would have.
