Sett W shouldnt gain grit off of damage taken by turret shots
This type of mechanic is already present on other champs in league, such as Yasuo's shield not blocking turret shot, and Morde only receiving 25% of each damage tick on his W from turrets and other non-champion related damage.
I'm just sick of Sett diving me and eating 3-4 tower shots only to have an 800+ damage shield at level 6, when I'm not even attacking him
