Refunding Champions

If you buy a champion, then discover you don't like playing him/her, you can refund your purchase in the shop. FOR A LIMITED TIME!!! I main aram, i have somewhere around 50 champs, for some god awful reason i get Taric like 20 % of my games. i bought taric a long time ago when i was trying to branch out, so long ago in fact that i cannot refund him. Riot will you please take Taric back? i would even pay you ip or rp. :)
