Cho'Gath Vorpal Spikes Tweak

I would like to make a small change to Vorpal Spikes.

Instead of this:

TOGGLE: Whenever Cho'Gath performs a basic attack, he will launch spikes dealing magic damage to enemies in a line in front of him.

I would like to change it to something like this:

TOGGLE: Whenever Cho'Gath performs a basic attack, he will deal on-hit magic damage and launch spikes dealing magic damage to other enemies in a line in front of him.

Essentially, I want Vorpal Spikes to do on-hit magic damage and the spikes launched to not affect the target that you are auto attacking.

I want to make this change because when CSing as Cho'Gath you can actually auto attack a minion that has low enough health to die to your auto attack and spikes but because there is a small window between the damage of your auto and the damage of your spikes, you can lose the CS to other sources such as your own minions.

While one could argue that this isn't a problem if you're careful, I think it's a pointless increase in skill required to CS as Cho such that there is a health level where you will lose the CS in between two ranges of health where you would get the CS.

This change won't affect his balance in any meaningful way.  It will mostly be a quality of life change for Cho players enabling less problematic CSing.
