Different idea for a Sion buff?
I'd love to see a way of balancing in collision of Sion's E with Champion minions (Zyra's plants, Malzahar's voidlings, etc).
It would almost make Sion's E count as a mini Kalista ult, and I'd love to see the different comp styles that would be created out of it!
A lot of people have discussed wanting the buff of Sion's W to be a 2 second explode again, but if you can find a way to tweak a play style over tweaking stats I personally always find it a much more interesting change!
