As far as throw, I really don't think we should be able to do that against anyone or anything that isn't both light, small, and at a massive strength disadvantage. Laezel throwing a kobold is probably okay, but throwing around anything bigger or stronger should be a monk-only kung fu thing. I really don't think throw should be a solution to maintaining the integrity of your position.
Well, throw is actualy just matter of few first levels (if you ask me) ...
Once you reach 2 (or 3? not sure right now) you get many other interesting toys ... thunderwave, pushing attack, repeling blast ... and ofcourse, there still are arrows of roaring thunder, or void buld.

To put it simply ...
I just feel like the game provides more than enough ways to keep your raft clear while you are unleashing havoc.

... So you can easily sacrifice shove.

:P
