Hextech trading system (just saying it would be pretty cool)
being able to trade different skin shards or champion shards to benefit others and yourself would be amazing. especially when you think about how some of the league community already has all the champions then when they open a hextech chest they pretty much get a useless champion shard for them but not useless for another. there can also be like requests and stuff. idk this just seems pretty cool having the community help each other out while benefiting them as well.
