You guys probably don't read all of these, but in case you do I have a suggestion:
Champion rentals! Basically, you could rent out champions for a lower IP cost so that us Summoners can more easily try an awesome champion out without having to spend a large amount of IP or RP on someone we are unsure of.
With the large number of champions out there (106 now?), it can take a while for a champion we want to play to go on their free rotation. Also, for those of us who don't play a lot or prefer to use RP for skins, it can take some time to save up enough IP, so when we purchase a champion, especially those costing 6300 IP, we want to be satisfied with our choice.
Any feedback is appreciation, and I would love to hear back from Riot if you guys see my post!
Thanks Riot for putting out some great material.
