Xerath's Rework

I've played Xerath for some games with the rework and I think the rework might have been a little bit over done. I mean now he is really easy to play (big range with no root on Q, auto stun on E, slow on W, auto root and OP range on R) you don't have to do any concession while playing it like you had with the root on W. Now it only slows you down a little bit and you have a 2 second stun on E.
My suggestion would be to make him slower while charging the Q (maybe like Varus?), keep the W (I quite like it) but change the mechanics on E so it does the same damage but puts the debuf (as before) on the enemy and you have to proc it with an other spell.
What do you think?
