Ember Fusillade seems to be missing a lot* more than any other spell I've used

I've had an enemy on the end of the screen be completely unscathed even though all of the projectiles launched at him, that same mob dodged another 6 projectiles walking towards me (none elite/super). Yes I was facing the mob as well.

The spell in general (perhaps I'm using or synergizing it incorrectly) feels woefully underpowered. The auto tracking seems to go awry, and most hits seem to miss whereas ice and lightning builds (this is around level 15) seem to work far far better. This spell just 'feels' very poor to use, lacking damage and accuracy, and when I equipped the support gem to fire 2 extra projectiles, I'd hoped it would fire more but it just charged 3 instead of 1 into the queue (which isn't inherently bad at all) at a time. Again perhaps I'm using this skill with the wrong synergies, but I have pierce and scattershot attached to it.

I just realized that perhaps that's why it appears that they're missing, although the monster wasn't dying so perhaps they are still missing.. but please investigate this synergy of skills/gems to see if it's working correctly, because it doesn't feel like it is currently. Thank you.

Thx and God Bless
