I, personally, thought the afk kicker idea was an absolutely ridiculous idea. I still do but, I can see where it has meaning.

However, as it stands, it'll be more of annoyance than helpful. First of all, the idea was pushed so hard when logging in was nigh impossible. Leading people to stay logged in. This isn't an issue anymore (at least not one that is anywhere near as noticeable as before). So, what's the point of the afk kicker now?

It's for people who afk during instances (duty finder) to try to ruin runs for other people.

So, rather than get rid of it altogether, reach a compromise. Restrict it to Duty Finder but lower it's time to 15 (or so) minutes from 30. Surely the only complaint then would be from the people who just want to grief?
