The fight being shorter doesnt mean you're less likely to lose 1 GCD though (as it isnt really something you can plan without knowing what you are up to)

You should just use fuma no matter what to maximise uptime, a few exceptions being:
-When you map a fight and see you can lose a bit of uptime without losing a GCD consistently,
-You're out of melee range

You'll find yourself in situations where its better to use Raiton when playing, its mostly a matter of experience so just keep playing I guess.
