Wepon deflect = brave
Gaurd deflect = centered
Dodge Roll or Glide away = scared
I don't mind getting attacked when I miss on deflecting. Heck, with MP Rage, you practically have infinite HP, especially with a couple of MP Hastes equpped as well. You get weak, use Cure, then getting attacked a few more times replenishes enough MP to use Cure again. It's those hard hitters that get me (like Kurt Zisa, which is why I used Tinker Bell), they usually end up taking me down before the animation for Cure is finished (or item use, in the Kurt Zisa battle, since I usually need curing when I can't use magic). Battle like with Sephiroth, it's okay to roll or glide away from. There's a difference between his attacks and Cloud's or Squall's (a BIG difference). So running away from some of those are better in most cases. I guess it all depends on the speed and strength of the attack, and on speed of the person in control of Sora (not everybody is good at Gaurd, and not everybody is good at Dodge Roll (I'm not)).
