Game is unplayable (at weekends)

I've played 6 ranked games today in low plat elo... and got afkers (and leavers) in almost every scenario.

To be more specific let's speak in numbers:

• I've queued in AND selected my preferred champs 9 times in a row
• the game was (actually) started 6 times
• both teams had to encounter with 7 afk players in 5 matches

5 OUT OF 6 GAMES was a complete garbage AND a waste of time... - that's more than 80% (!)

CONCLUSION: look at the title...
