Client auto-repairs on match start.
This is the second time League has decided to repair the installation right when a ranked match starts.
Both times were Ranked matches, so I lost rank.
On top of that, I get low priority queue! The first time was 5 minutes waiting period for five matches. Now it's 10 minutes for five matches.
Are you intentionally trying to piss off your client base?
I was considerate enough to post this when it happened in a similar thread, but after discovering that the wait times had been raised for something I have no control over, I had to start a new one.
Maybe I should just make a "League yanks my chain" club, and we can start putting all this crap into a nice useful list, for purposes...
