Shens Shield needs to be stronger(HP Scaling) with longer cooldown for better windows of power
His shield needs to scale with Hp and Ap like Skarner, or just hp(or maybe a % of ar/mr??). It's currently too weak, and should absorb more for it's cost, with a longer cooldown for better "windows of power" or whatever phrase Rito says is healthy.
His passive's cooldown is reduced by 1 second per basic attack and 2 while the shield is up but quite honestly it's usually popped instantly because it's so weak, therefore this part of his kit is rarely utilized in pvp combat.
I feel that a lot of this ability's potential is held back due to it's counter-productive short cooldown, because after Shen's initial engage he's stuck waiting to use one spell at a time, which as a support tank is really lacking in the current high-standard meta.
A simple tweak of adding an hp scaling to it's per-existing base+ap scaling, at the cost of a longer cooldown would be a huge overall improvement to Shen.
P.s. I also feel his Q self-healing should be increased to 150 if not 200% against enemy champions.
