I feel Like Match Time has Gone up since last Patch

The last few days, I've felt like almost every game has lasted at least 45 minutes. Most teams carry at least two hard lane pushers (Iggy, Howitzer, Bellica, etc.) and then they never leave their lanes, so it's just a slow back and forth until someone backs at the wrong time.

Did they count surrenders as part of the match length before? Because people aren't surrendering as much not because, even if they are super far behind, a single team fight can make it so they can kill 4 towers and gank the core.

I think the paper towers made the problem worse, honestly. It discourages team fights, because leaving a lane is asking for a tower to be instantly destroyed.
