[Spheres of Power] homebrew fixes to Telekinesis?

I love the Telekinesis sphere, but it just has so many issues. it's really convoluted, talent-heavy, the early levels are weak and the later levels are absurdly powerful, there's not really any ways to spend SP on regular attacks, and slow BAB pure casters are at a big disadvantage and really can only use excessive force or sweeping bludgeon. I'm curious as to what homebrew fixes people have for this?
