Champions tag-team combos?

I don't know if this has been brought up before, but I searched Google and couldn't find anything. Matter of fact I couldn't even find out where the appropriate section was to suggest new features for League of Legends so I apologize if this section is not fit. Feel free to move or delete ~ not that you need my permission but i'm that kinda guy. :p

Anyways to the point. I was thinking that we could get duo combo's implemented which would highly increase teamwork plays. Now this could be very hard and also exploit some superior combos but I think if properly adjusted it would be amazing. "What do you mean by 'combos'?" Well let's say Ziggs and Tristana are laning together against 2 other whoever champions. Ziggs and Trist would pull off a "wombo combo" where Ziggs throws his iron grenade in Tristana's cannon which would result in an instant global pentakill... just kidding, relax. It could be something simple but I think it'd be cool and would allow players to try out new duo champions just to find combos. It'd also make amazing video montages :p However the downside is bot lane is going to be on a whole new level - whether that being good or reported 9x lmao. There are quite a few amazing combos you can pull off already but I want something that actually involves in ability modifications.

This was only an idea I felt like suggesting - feel free to collaborate in anyway. Tell me why or why not that this is a bad idea.
