2 Ideas for Shen
- Make his ults shield durability (not amount) scale with either his armor/mr or his HP.
Right now his shield is easily melted through by just about anything. It's nice that it's an instant shield and global but when someone melts it down in .2 seconds 
it's not worth the cd/ability to be canceled/inturrupted etc. It would make his shield unique as he'd be the only one with a shield that actually has tank stats on it. I can see this being a huge pain early game so I could also suggest removing the ap it scales off of completely but increase the base stat slightly so it wont be useless.
- Allow his E to refund like 5 energy per monster hit but 0 for minions. Allow it to damage minions/monsters. This will give shen decent waveclear but at a cost of losing all that energy + his escape which has a long as hell cd. Since the largest jungle camp is raptors he'd only get back 20 energy at most. This would help shen become a better jungler as well as top laner since even with cinder his waveclear is immensely bad compared to just about every other champ in the game
