Really strong footsie game that lead into damage and knockdown into wake up stuff in A3... Plus her V-Ism stuff was a lot of fun back in A3. If you played Alpha 3 and used Karin, you'd understand how much fun it was to play as her, thus you'd end up wanting to have her in one of the current games due to a strong attachment to the character. Personally, I played Alpha 3 a lot and I loved all the sick options Karin had, while also having one of the strongest footsies in the game. Karin is still my #1 favorite SF character from a design and gameplay perspective. Sure, other characters have rekkas, but the way hers work tied with the way her normals worked is just perfect IMO.
