Siege Cascade in combination with Scattershot does not work - no extra projectiles

Hey Support-Team,
I just wanted to inform you that Siege Cascade does not work with Scattershot Support Gem together. There are no extra projectiles flying (+2) due to the support. It does slow down the attack speed, but does not do extra damage cause of missing additional projectiles.
Would be great to see a repair for patch 0.2.0 - wanne play the combination! :)
Thanks mates - keep your good work up!
