This is quite literally the first patch I've actually been excited about for League since they added intermediate bots. Compared to previous patches this one's quite hefty too.
I love the new queue for ARAM - mostly because when going through the usual custom game route, it took around 4-5 rerolls before you could expect to play, due to there being no penalties for leavers. Kinda takes the fun out of it being random when people are just going to leave games until they get what they want. I also like the concept of being given rerolls for playing games, based on the # of champions you own. The new map (replacing the Proving Grounds) is really awesome too. The towers crumble! :D
