New Game Mode Please!

Is every game mode except URF and All For One the only fun game mode? Would you like a new game mode where you can buy the same items more then once and the effect of that items would stack or apply? Bring Back Items that could stack, there need to be a game mode where the player can stack the items however they want. There is many items in the game we wish could stack and go wild with it. Example: Rapid Fire Cannon: The item passive that would add bonus range when charge would make ADC have so much range when a player would have 6 Rapid Fire Cannon, by doing the math means 150 range bonus for one items and you buy 6 would mean you get 900 bonus range making all ADC unreachable from any Assassin. Let not forget #ADC2K17 ADC might have Rapid Fire Cannon but here support can be just as strong by having 4 Knights Vow, a support could put it on ever teammate meaning the support would be healing for the damage and at the same time getting tanky from the bonus armor. Let bring this game mode to life and not have old game mode in the rotation that not many people play. What do you think? Should this be a new game mode?
