Shen rework is fantastic <3 I learnt to love the new shen and he is stronger that you may think :) ( Still miss the old shen tho )
Just yesterday, Playing casual game with him : 11 / 2 / 16 -- 3 / 0 / 5 -- 17 / 4 / 18
13 / 3 / 18 -- 4 / 1 / 7 ( the last game I was splitpushing all the game and protecting my adc when needed. He was untouchable =-) )
Probaly because I main him... But most of the time I carry.
He isnt bad at all. Only overshadow by op OR Meta champion.

for exemple :)
New shen need A lil more skills and dedication to be at his full potential. His early is quite strong. If your opponant take 3 emporered Q, he probably lost his lane unless you play like a dummy.
Once again, I main him ^-^ ( Almost 200k mastery with Shen )
