Shen Main (EX) - Gold - Thoughts on 7.8 Shen Changes.
The changes kill top lane or jungle Shen. Short and simple.
I've never, not once, heard someone say "You know what Shen has? A lot of built in wave clear." It's more along the lines of "He's not exactly the greatest at farming, but he's okay at it once he gets sunfire cape." An item available to anyone really. His Q was his only effective way to farm, and it was significantly nerfed. You might as well not even bother Q'ing while trying to farm, you gotta save that energy.
His E buff was nice, but not huge or anything to balance out the Q nerfs, and lastly; his ultimate nerf(Literally).
A 20/30/40 second difference between the previous cooldown & the current cooldown, not to mention, a base shield difference of -75/-200/-325. Sure, when your ally is on the verge of dying, those numbers change to +30/+10/-10. So, increased cooldowns and decreased shield effectiveness late game, and the notes even basically said he's only really decent at the organized level. So yeah, my opinion (That's all this is, the opinion of someone with 200+ games on Shen) is that this massively hurts top lane or jungle Shen. Support Shen has possibly seen a buff with the E buffs.
