Lissandra Ult: bug/oversight?

Not sure if this is intended, however it** IS** annoying.

But when you go to ult (targeting or smart-casting) on an** enemy champion** that dives you, there is a tendency to** click yourself** EVEN if you wanted to click the enemy.

I find this awkward as I generally** Alt+Click **my abilities to self-target.

And when a Zed or Panth jumps you, it's quite annoying to click yourself and lose that kill.

Is there any way to make the ability target ONLY enemy champions unless Alt+Clicked?

I only ask because it seems to happen far too often. (Not sure if the hit-boxes get so close together that they 'merge' briefly..but sometimes I could swear I clicked the enemy, and yet I cast the Ult on myself)
