I wish Riot would implement a mechanic where you are allowed to 'sell' a champion (i.e. lock them back and have your ip and rp for skins returned), I just bought Akali, Ahri, Irelia, and many small cost champs which I honestly am not going to play cause of nerfs or they don't match my style of gameplay, I wish I could just sell them so I could just buy champs like Xerath and Vel'Koz without going through the pain of many games or paying to get them...
UKP LK3 votesikr, the refund thing is so bad only 3 times, I bet even rioter make mistake more than 3 times in their lives. I vote for this, at least let me sell them for 70% price or sth -...- I have so many champs I dont need and alot I need but no monay T___T
GiveMeUrMilk1 votesWhy would you buy a champ if you know they don't go with your preferred style of gameplay?
Hencho1011 votesA while ago a was like "oh ill buy 
cuz she looks fun and can fit my play style" i have made an oath to NEVER play her again. holy SHIT, FUCK that champ
GiveMeUrMilk1 votesBut why? Thats what you need to take from it. Rek'sai can be a fun champion. But she has been gutted so hard that its very difficult to play her unless you know what you're doing. And it's not much fan to play her for more than a game at a time.
But this scenario is why I always tell my lower level friends to wait until a champ is on free rotation to try them. So they don't end up buying a champ that they don't like.
AwareChill1 votesWaiting is too much, also I have played ahri and xerath before on free rotation, they were fun but unfortunately ahri and a good item for her are about to get nerfed and its believed she will be bad to play ranked, so essentially the moment I bought her and started to practice with her she get nerfed to azir's point so I wish I could trade her for someone else
GiveMeUrMilk1 votesI have seen no nerfs for Ahri on PBE. Even if one of her items is nefed she will still be strong. She is a jack of all trades master of none. and is a safe first pick in midlane. No, she is not getting azir level gutted, I guarantee you that.
Yes waiting takes a while, but its better to wait then spend recklessly on something you don't like and may not be able to refund.
AcidTheWarlock1 votesYep. Upvoted.
Bhagswag1 votesWill never happen.
Also, some 6300 champs are boring to play while some 1350 champs are super fun. You really just have to play them all to see.
