Shen's kit missing some dynamic scaling

Right now there's no reason not to build CDR and less so attack speed. The utility from CDR is too beneficial.

What I liked about the old when was being able to build various ways. If I got attack speed I could heal more and reduce CDR on the old ki strike.

I was thinking it would be cool if bonus attack speed helped lower his current passive cooldown, or give him a bigger shield. (This would be exclusively from items not from allie buffs like 's W or bloodboil).

A bit like q scales off bonus attack speed.
