Asking an obvious question

It blows my mind how much of a nosedive Ranked games take from weeknights to weekends. Are other people seeing this?

5 games on a Tuesday? Seems fairly balanced.

5 games on Saturday night? No one has a mini map, no one pushes towers, no one groups, and any time you're 3 to 6 towers behind, we have 2 to 4 kills and it's immediately "WE NEED DRAGON!"

Basic gameconcepts just seem to go out the window. The weekday people can't be all gone, can then? What is going on here? I just go TB on the weekends now because at least the "but kills will help us _get _towers" crowd isn't screwing up my score.
