[Rotating Game Mode Concept] Game of Chance!

This is a concept for a mode I think would be cool to add to the rotating queue at some point.

For this mode, instead of selecting a champion at the lobby, you instead select the role of character you want to play. (Fighter, Mage, Tank, Marksman, etc.) This decides what characters you will play throughout the mode.

What I'm proposing is a game mode where every time you die, you will respawn as a different champion (levels, items, and skill point allocation stays unchanged) based on what role you selected at the lobby. If you chose Mage, you will only go through champions with the tag of "Mage", the same for "Assassin" and all the other roles.

Instead of a normal shop, you will instead be able to purchase consumables, trinkets (and respective upgrades), and random chests that grant items based on which chest you purchase. In example: Say you buy a "Boots Chest" you will get any one of the boot items, and then be able to upgrade it as you please normally. If you buy an "Attack Damage Chest" you will get any one of the attack damage items up to things like Tiamat, but not Titanic Hydra-- You would be able to upgrade normally after you have the item from the chest. Any purchased items cannot be sold in this mode.

Champions who have items that are unique to them and only to them such as Viktor will be banned from this mode to avoid complications.

Unlike normal modes, this could allow all champions on a team to be the same all at once, but will change upon any single death.
