If I go on vacation, I don't stop breathing. I'll likely be a bit busier with other things, might have a chance to pop in and make a few moves here and there, but mostly I'll be afk. I might even pop in and play one person, just to give them a shout (game message) about something. You seem to be saying 'vacation' equates to self-induced ban for XX days.

There are only so many vacation days -- use them unwisely, they're gone when you need them. Playing a light load while on vacation should not be a crime.
