League Client just sucks
Seriously, the amount of times the league client crashes is pretty unacceptable. The game's been out for 10 years and still, you can't reliably queue up without the fear of crashing and your team remaking. I've lost promos because of this in the past and just lost another game. I know it's not my computer because it's as compatible as it gets and is up to date in every way, shape and form.
I realize this won't get addressed but come on Riot, fix your damn client. It's been long enough.
