Abnormal amount of Dodge/AFK in ARAMs (Player Behavior)

Hello everyone! This is mainly targeted towards Player Behavior. I am posting this in Gameplay & Balance as I did not see a Player Behavior forum.

One of the things I loved about the game was the fact that I could queue for ARAM instead of running in custom modes. In custom modes you constantly had people dodging the games if they didn't like their composition or champion that they got (everyone wanted Nidalee, AP Yi, Katarina and the likes). Fast forward a few months and it became a dedicated queue. This was awesome! I spammed games non-stop. I helped people learn the game mode. I gave tips that were mode specific. All-in-all it was a good time. I acquired all the honor ribbons (lost over time). Queue dodges were down.

Fast forward to a few weeks ago and 4000+ games played.

A couple weeks ago I started noticing that there was an abnormally high amount of dodges in champ select. This doesn't effect me that much as it's not my queue time that increases, just wait time to get into the game. It's about every queue there is at least one dodge. Sometimes multiples but statistically it's one queue, one dodge.

While all that is mildly annoying to deal with to get into a game, once the game starts itself you have people that either DC or intentionally AFK either at the start (team comps) or after a little bit. Now it becomes a very frustrating experience because you are playing a 4v5 (and while I'm content to either play it out or let them push to win, most of the team is not). AFK's (on either team) seem to have increased as well. I know most people will say that it's frequency illusion. I do not believe that's the case. I've a pretty good memory and while I've had my fair share of AFK's over those 4000+ games, during these last two weeks there has been a higher increase. I'm willing to go out on a limb and say that 1 out of every 3 games I have has someone AFK for atleast 10 minutes per game if not the entire game.

Now on towards the main reason for the post.

Is there something that Player Behavior could be noticing in these increases in AFK/Dodge due to game modes or something else? I'm trying to figure out why there has been such a higher increase (maybe the Mark/Dash addition). Anyways just what I've noticed and wanted brought to your attention.
