Shen needs an HP nerf... That's all!
Shen losing his lane sustain was already a hard nerf enough because it's not easy to ultilize his passive and W to negate dmg in most situation, not to mention his base hp and armor and hp and armor per level. That was a tad bit too much. His new W is not as strong as it may apper it's very situational. All I ask is that you buff his base hp (not per lvl)
So he is not as squishy early game and can take a betting more (He'll still be squishy, but atleast he can take a bit more)
Base Hp 540 to 600
Trust me rito, I am a long time shen main and have a PBE acc. Didn't get to try him out and give feedback on pbe cause the patcher always failed on me but i'm telling you now and that's what's important!
