It's the same for me. I feel really comfortable playing Momiji or Nyotengu, but I know it's a bad habit to reach for 7P whenever I'm in danger. Especially, when I use Hayate...
Exactly. Now here's another thing. The command for the Critical Burst. My muscle memory is fixated with 6P+K being the initial CB(I've played with Kasumi & Hitomi who have 6P+K as CB). Since I'm playing Momiji, her CB is just P+K. Sometimes I get it, while others I accidentally press 6P+K when I go for a CB setup.
