I have a VU idea for Ashe

Yesterday ProphaneProphet started a popular thread on which ultimate abilties don't have that ultimate feel to them (an "oomph"). That got me thinking about Ashe's ult - it's a gigantic arrow that sorta explodes when it hits a target, which sounds cool on paper but looks pretty bad in-game since the explosion itself isn't proportional to the SIZE of the arrow.

@Riot: How hard would it be to change it like this: When the arrow hits a target, it shatters into bits and pieces, maintaining its momentum as the icy chunks pass by/through the target and scatter into the air, leaving a frozen statue of a champion. Give the target essentially a Zhonya's retexture, so it's icy white instead of golden.

This was partly inspired by Borderlands, where you can shatter frozen enemies into chunks: http://www.dealspwn.com/writer/wordpress/wp-content/uploads/2014/10/cryo-540x355.png

What do you think?
