Idea for a New Game Mode

So I love playing league, and most of my games are played on the ARAM map. The main thing that draws me to ARAM is the idea of random champions which helps to eliminate the OP champions that appear 95% of the time in other game modes and in normal games.

I was considering the idea of a game mode that would be set on Summoners Rift and would give a random pool of 10 champions for each team to choose from. The teams would take turns going back and forth picking a champion one at a time which would then lock that champion from being picked by any other player on their team or the other team. I think this could be a really fun mode and would help to eliminate the perma pick champs that we see so often in other modes.

This idea would also open the game up to some fun builds and strategies that many players may not otherwise consider experimenting with. For example, one team may try to take all of one specific champion type such as ADCs in order to deny the enemy team that damage type but would then end up leaving themselves very squishy and without much built in protection or sustain. It could open the door to being able to try crazy roles like say, Soraka jungle because you don't have to worry as much about an actual jungler invading you because the enemy team is running jungle Janna. It would also allow people to try off meta roles without other players raging and accusing them of making troll picks.

I think it would be a really easy game mode to implement seeing as you aren't really changing any stats, etc. like you would in URF or One for all. It could eliminate some of the frustration other rotating game modes such as Nemesis and one for all have, where you can occasionally feel like you are stuck with a champion you hate because somebody else picked it for you. At least this way you are given options to choose from a pool of champions.

Let me know what you guys think :)
