User blog comment:M.Davidz/Need your help for Shen !/@comment-24795478-20141114040709

first of all, shen is all about full tank and sustain, so dont bother giving him any mean of increasing damage, as that's not his playstyle. You're right about his energy cost is too damn high, but i dont think change the AP to AD ratio will fix the problem. If it was AD ratio, the result is still the same. No one build AD on him.

About your skill set change: And post this idea onto LoL forum, maybe it will get noticed.
 * passive : as i said above, AD is useless on him. and 76 bonus damage without building anything at lvl 18 is a great passive already. No change needed.
 * Q:same as above, 7+0.5 max hp/sec is strong enough
 * W: 220 base shield is strong, but AP ratio is sure useless. Maybe add 10% bonus HP scale? ( nautilus' shield is 300 base and 10% bonus HP scale, and also give damage)
 * E : good though
 * R : no change needed, maybe just reduce the casting time to 2 is good enough.
