Entropic Sphere Bug

So, I've been playing and absolutely loving the game so far. Nearly 60 hours into it playing a mage, and I went for the Evoker specialization. I have come across a strange interaction that I believe to be unintentional. When I first got the Entropic Sphere spell and started using it, the projectile traveled fairly slowly. Not a problem, in fact I believe that was intended so that it would stay on the enemies you wanted to hit with it, and at the speed that it was traveling it had a sort of affect that pulled enemies towards the center of the AoE as it moved.

Now, here's where the bug comes into play. As I kept leveling I found some upgrades in the skill tree that increased the radius of the spell. Each time I increased the radius the spell seemed to move faster to the point that it would go past the enemies and go much further than what I believed the range to be. The problem that came up with this is that the suction affect was too slow to keep enemies inside the radius while they are trying to get to the player to attack. This made it so that the spell would hit them for maybe two seconds and then already be past them, which means it does less damage AND it wouldn't apply the weakened primer status to them because that's only applied on detonation not first contact. Even though the radius is much larger it now moves too fast to really hit anything with. But taking the AoE increase off will reduce it on other spells I am using. Not sure if anybody else is running into this problem? I'm hoping EA can find a fix.

TL;DR Evoker mage has issues with Entropic Sphere moving too fast to really be effective if you upgrade the radius in any way.
