Improved Pick Trading
Picking champs and then trading them is an under-featured part of playing Draft solo-queue. To do it, you must own the champion someone else wants, pick it whether it fits your role or not, and then trust them to trade with you. Adding a client feature could solve this problem: a trade offer.
To make one, you could just click on a fellow player, scroll through a miniature champion menu to select which champions you two would have, and then click send. They would get a window with the option to accept the offer, which if clicked would make the client automatically lock in the indicated champions on the respective turns in draft and trade them after champion select. Neither you nor the other player would have to own the champion that you would be trading—only the one you wanted.
This feature would solve the problem of not owning the necessary champions or fearing that the other player might troll you, enabling all players to play draft like it was meant to be. What do you think of it?
