I got a feeling that the matchmaking is way worse on weekends then during week (during week I play in the evening).
During week I can feel at least some kind of konstant skill on both teams (of course there are some exceptions). Most time I get matches which seem to have at least some balance.
But on weekends it feels like the enemy either has a wallhack or is playing with a steering weel. It happens rarely that I get a match which seems to be balanced. Either my team just stomps the enemy team or we are getting stomped.
Anyone else who noticed this? (I play on EUW)
