What I have learned from playing the latest itteration of URF (SAAAALT)
Is that any semblance of teamwork, outside of playing with people that you know, is just non existent in this game mode.
Start losing lane? Ditch the person you were in lane with and then whine about how fed the enemy team is from that lane. Oh and go into the jungle and feed other lanes, since you know... your underleveled at this point and you wont go back to your lane.
It is just beyond tilting when, with no prior communication or anything, the person you are in lane with just leaves. Is just gone, and all of a sudden you have two broken beyond all recognition champions pummeling you into the dirt, and then you get pinged for dying. Under tower.
That and all random is just... stupid. It takes all the little fun you can get out of a game mode, that isn't even meant to be taken seriously in the first place. It's supposed to be a fun, mess around experience that just comes off as a eighteen minute stomp-fest for one team because the RNG decided to bless them with an impossible to deal with team comp. Oh and you rolled Nunu, so have fun with that.
