Deep Elf Infiltrator Upgrades

I have limited experience with this champion, and would appreciate more input. Are there any preferred upgrades? I'm inclined towards Shadow Shift and Stun; is there a solid case for Hit n Run or Paralyze?

 

I think you need shadowshift, stun or paralyze are whatever suits you.

 

I run paralyze because it's cheaper, but w/e suits you, I guess.

 

paralyze is the best since it has range and is cheaper, the only downside is you can't hit the target again without removing paralyze and it's 2 more ap than stun. the ap though is made up by the range
