@RIOT Ever thought of some class locked items?

When a champ is created i'm pretty sure you guys have a clear idea of what he is going to be; with few exception ( like Varus, as you stated ).

What i would like to know is if you ever thought of adding class locked items that only a champ of a specific class can buy; adapting to his the relative subclass.

Like for example:

Wardens and Vanguards, on the Tank tree, will have acess to the same item that will grant bonus P. and M.Def unlocking a specific ability based on the champ subclass;

X Item Name for Tanks

X Armor X M.Res Effect: Based on subclass

For Wardens Reduce all incoming dmg by X% _For Vanguards _ Reflect X% of all incoming dmg

Items like this will make the game healthier, and since the item will affect a lower roaster of champ it will be easier to balance, it will also prevent overabuse like the case of Tanksuo and Tekko.

Building these items, obliuviosly, shouldn't be a must, but it should help specific classes to do their role better
