Shen rework abilities barely scale...

What I mean by this is that there are so many components of them that don't scale with level point in it. For example, each of these components do not change from level 1-5 of ability.

Q: The slow and attack speed bonus.

W:Energy cost (understandable because it's very low) or length of time. Honestly this one is tricky because if it scaled to something like 3 seconds of no autoattacks that would be way too long. No ideas in how to make this one scale other than increasing size (which I think it does?)

E: Energy cost, taunt duration

R: I think this does not need to be changed, but nevertheless I may as well just say that the shield time and channel time don't change.

I mostly think that the Q should have more scaling, like maybe start at a lower attack speed and end with 80% at level 5.

P.S. Does it seem strange to anyone else that the spirit blade doesn't deal damage if it hits a champion? I understand his empowered basic attacks are even better if he hits one but I feel like the blade should at least do a little.
