I was thinking, first of all; eles really, desperately need a great sword... permanently.
Not talking about the elite skill.
Secondly; the elementals spawns need to have infinite time manifestation, and instead, just like necros, they would have a health bar instead.
Last but not least. I would replace some weaver sword skills with better, awesome skills; such as a homing meteor that would cause a great blast and damage, but long time recharge; a sphere of electricity that would stand in mid air, releasing lighting bolts in different directions; a geyser that would knock down foes, etc.
Just a few ideas.
