Shen changes?

I can't be the only one that thinks needs something done to him. I'm not saying he needs anything major done, but he feels like he is weak. Unless your team is ahead then his impact is incredibly small, and that his kit is fine, but his w feels so weak (impact isn't that visible with high cd and short duration), and if you miss your taunt he doesn't bring much else that's anything special, other than his ulti (q, his only real damage spell is just abysmal.) His damage is the worst out of all top laners right now while not having a lot of cc. (he is literally last, at 48/48) He doesn't even tank that much damage out of the top lane pool (he is 30/48), which is pretty bad considering he is meant to be a brick wall. Win rate is sitting at 47% and he is 2/48 for most deaths on average. The only overtly positive thing you can note from his stats is that he contributes to a lot of assists and has an above average play rate, especially when you factor the above in. I dont know exactly what NEEDS to be done to give him a nudge in the right direction, but he is just a hot mess of a champion that feels great to play and is really fun, but overall he is just a little lacklustre. His damage says hes a tank, but he only has one hard cc. His abilities scream dueller, but his damage isn't there. He has such a good play rate (10/48), and he wins in the assist department, but his win rate doesn't reflect this and his other stats suggest he is lacking. He is just one hot mess of a champion.

TL;DR - I feel shen is weak(ish), do people agree? And what could be done to improve his play?
