Just got ninja'd by Force. Haha, how ironic. Turtling is a misinterpreted game term derived from Spacing. Should you let your opponent hit you? No, not at all. Should you get the drop on your opponent? Yes, yes you should.
Well Momiji and Ayane both excel at the spacing game as well as forcing ppl into mistakes...But turtling as a whole is good tactic especially if the player doesn't know how to deal with it
