Void sphere of rending... what is going on in here?

higher damage and added damage multiplier at the cost of area of effect and low duration seems good at first glance but the skill is still locked to 1 void sphere at a time. damage wise is still terrible or i am missing something?

also whats up with the quality? standar void sphere quality got changed to cooldown recovery but void sphere of rending has no cooldown and neither of the stats displayed seem to be buffed in any way.

Qual now increases the "of Rending's" AoE, making up for this version's major shortcoming.

I'm a huge fan of Void Sphere and feel like it's seriously hindered by the high CD. Was very excited to get this as an option in Lab. I've been trying it out, it's fun to have to strategize dropping it less than the normal. Using Inc AoE, Phys to Lightning, and Overcharge. I'm still in campaign tho, will see if I can keep using it instead of Ball Lightning as the trigger for my pets.

Eventually I'll revisit the Void Sphere build I saw about a year ago, which took way too much effort to reduce its CD to roughly its duration. This one might actually be viable, but the "only 1" really does suck and is probably what'll make it not so much.
