TL;DR Shen's E width is increased, so that it can actually hit champs.
However, his Q no longer does bonus damage to minions, and his ult shield is nerfed mid-late.
I legitimately think they've killed off Shen. His one saving grace in laning phase was CS-ing under tower, and they're planning on taking that away.
Yeah, I get it. You're balancing him for pro play (hence ult nerfs). But was his Q nerf really necessary?
Edit: I missed the flat bonus damage to all targets on the tooltip (and so did surrender@20). My bad.
