It made sense not to have one for Final Fantasy XI where bazaars became important. Bazaars don't exist in 14. GW2, WOW, and SWTOR have auto-kick, so it's well precedented.

I don't see the issue. It is extremely easy to log back in. If you aren't around to press a key every 25 minutes, then you aren't around to accept a duty finder invite, either, so I don't think that's a good justification.
