Really don't like new Shen
He feels too gimmicky, like everything revolves around placing his spirit blade. If i didn't know any better his Q and W were literally Orianna's ball.
So he loses his ranged poke Q which was like part of his identity as a sustain tank, being able to stay in lane if played safely even against champs like vlad, quinn, etc top. Now he has a slow spirit blade that he needs to base his W off of and has to do the ever-so-redundant 3-hit autos.
meanwhile:

all get to keep their ranged Q harass/poke.
His W is probably the only thing I find interesting or pleasing. While he loses his shield, he gains an ability that allows him to interact with the opponent and even his own team. but even then it only does anything against basic attacks. skills and spells still hit you. Shen's literally lost all his pressure. He has to literally all-in you to do damage.
His old passive was great, it was his damage, being able to do a mild % of his max hp as damage and staying in the fight to reduce its cd with basic atks would be rewarding. Now I have to waste energy to do damage with Q. Not to mention his new passive's shield is time lagged if you use his Q on it, only activating when the spirit blade actually reaches shen, so if it's at a mild distance, chances are it won't save you, r if you had to blow all your abilities already, you won't have a shield off cooldown
His taunt was nerfed too, it hitbox is narrower. not only that but you removed the reduced damage that made his quick trades good.
Played shen in some 3's and SR today... and honestly I did not have fun. It felt like honest crap.
EDIT:
his W and E cooldowns are high, he can't even engage meaningfully with those.
Also, he's a fighter now..... but he has no sustain whatsoever.
meanwhile
passive and ult
passive heals a ton
W passive heal
these guys are tanky fighters and they get sustain, why was shen's removed?
