The Shen Rework
He is no longer a safe pick and is easily hard countered. Old Shen was countered as well but it was doable. Ranged champs could give him a hard time early game or it was a neutral lane but now this is not the case. All someone has to do is pick Pantheon/Quinn/Gnar/Vlad/Teemo any kind of ranged/poke champ top and just dumpster Shen early game.
Shen definitely has the capability of being a beast late game as long as he is not shut down. It's just going to get even harder for Shen during the early laning phase. His old shield could have been used to block certain skill--shots or point & clicks (pantheon) this is barely an option now. His passive shield only comes up if a skill is used and you have to be inside the spirit-blade circle in order for his W shield to protect you. Essentially Shen is going to eat a lot of dmg.
AND correct me if I am wrong but his E has a 2 second increased CD time. WTF is up with that?
When he is released (cause lets face it, Riot is totally going to release him like this). There will be a lot of feeding, of epic proportions lol.
