FFS mode (F(riendly) F(ire) S(hoot em' up) game mode

This is an idea I had where, all abilities could hit allies there are no point and click abilities here, go to ram your enemy as allistar but your ADC is standing in front of you boom now they are in the middle of the enemy team. Now while this game mode may seem like it will only be for extreme trolls, maybe that's a good thing. There would be less trolls in the actual game but also sometimes trolling your team is just really funny let's be honest we have all done it, even dyrus has openly admitted to doing it. Now maybe you think but that is way too op. Well for ults maybe those dont hit, or maybe allied champions only take half damage or even no damage but any kind of slowing effect will be applied. Many game modes in League of Legends seem to have a certain purpose that will help you with mechanics in Normals. For instance ARAM while mainly played by people who enjoy league of legends but dont really like the competitiveness of League but still enjoy playing, can also be very useful for learning when and how to teamfight. Have a squishy mid laner? Did you go in front and try to lead your team into the fray only to be 2 shot by the opposing team? Do that enough times with a champion and you will learn "Hey I have really good poke damage but I get hit hard, but that champion there can take a boatload of damage and still walk out, maybe when he goes in I should try to poke" Boom, mechanics learned about that champion. Well this game mode will be EXTREMELY useful IMO for learning how to line up skill shots. How many times have you gone to take a skill shot thinking it would go between the minions only to realize that it has a slightly wider hit box than image and the enemy ADC got away from you. How many times...........kajsnglfahogheaorjaerojkl. Well this game mode will make people attemption to improve their skillshot taking have an easier time at it. After all now you are not just trying not to hit the minions in what may be a few times a game situation, you even have to be careful not to hit your teammate. AS for the map this is played on I believe something like an ovular arena with narrow lanes would be best, maybe 2 turrets per lane with the tier 2 guarding the inhibs and 2 turrets still guarding the nexus, in the center and spread out in 6 places (3 on each side) would be large circular areas with nothing in them. This is just an idea, comment below if you have any more ideas to improve upon this and hopefully a riot employee will take a look at this fingers crossed.
