Shen Coming Back Into The Meta?

Okay, right now (atleast in EUW) Assassins are winning alot of games, Zed, Talon, Kha'Zix ect.

So to counter that Shen would be great.

Tanky+++ Taunt(Hard CC)+ AoE Dodge For Entire Team++ Global Ult that can shield up to 700 damage with no AP+++

This combined with the fact that tank jungle/top is sort of coming back shen is a counter to all of the above.

No he doesnt counter mages, unless he can taunt them.

What do you think is Shen good?
