Can we change Shojin to only block physical damage?

ADC's burst people down like a goddamn truck, assassins are getting indirect buffs with the itemization changes... Meanwhile, mages are continually getting nerfed. Not directly. However, mages pop like a balloon in a shredder to assassins, who can dodge all their skillshots with one button press and leap onto the enemy. ADC's just have to get in range to auto and they've done 30-40% max HP.

Shojin will render all DoT based champions utterly useless. Cass, Teemo, Morde, etc. By doing calculations I figured out that a mid laner with only Shojin and Dblade will block about 40% of Cass's Q damage, plus 30% of her E damage if they are both at max level. Essentially they're purchasing 150-200 MR, but also getting attack damage, health, and CDR.

If Riot keeps this item in the game, in the state that it's in, they're either retiring these champions for good, or they'll have to do serious changes.

Changing to physical damage will allow mages to be more influential in the game and give them a more important team role.
