That's true when it comes to projectiles. 

I'm more certain that his fireballs would slip right through the smoke and hit those behind it... for low damage as he split it up xD... its a hit at least.

Perhaps if he used like Gust or something he could have blown the gas away xD

Ember has always shot more than one projectile however in the anime hasn't it?
