I give up from playing urf tbh

Like for real, I always get the same champions, always the free week champions I just wanted to play some Riven in urf, I swear, in about, 30 games of urf I got 1 time Riven, and they dodged, they dodged, and then I get Tham Kench, AGAIN FOR THE 6TH TIME. I have no rerolls, if I dodge I lose my rerolls when I reroll, and get a timer, I swear Ar Urf isn't fun anymore, yes the first games are but then you are sick of getting the same champions over and over again. It gets annoying sincerly. If you want to do something called "Random" at least use the entire inventory of the Summoner and not prioritize the Free Week Rotatio. Aram is okay to have the prioritize to Free Week rotation but just re-use the Aram Randomness isn't really fun in urf, especially when there's tham kench in the free week. It can be Random but not prioritize the free week, that's just.. annoying.
