Two Champions Played as One?

Basically, your mouse controls two champions, but they stay together. Each has a different health bar. And instead of a mana bar at the bottom, it's a second health bar. They have less hp than normal champs. When one dies, you can keep playing as the other. (Or, if one dies, the one alive absorbs the dead one and becomes one bigger champion and then goes back to normal after death). Very complex, yet seems entertaining and fun. R should be a switch between each of the two's kits. Build on this if you'd like. Provide constructive criticism. No "your idea es muy muy noobo si senor". Simply a "While your idea has good ideas in it, I do not agree with the concept because it is far too complex for the average player."
