There is no shifting metagame, instead to shift playstyles and prevent it from acting like a solved game they patch it every week.
Doesn't make it better. I don't mind people playing it since a bunch of people I know in real life do, but it still is a weak game.
Not compared to anything. It's just a weak title because it's not incredibly well made or anything. If you want a comparison, compare it to Dota. It's a Dota clone and does everything worse. In Dota one build might beat another build but will lose to a third one. In LoL builds can be objectively better than others meaning there are fewer ways to play each champion than there might be if they thought out their item base a little better.
everyone i know plays LoL, and i've grown to hate it because they all want to play that awful game for hours and hours instead of talking to me i refuse to ever, ever play it
