Agree whole-heartedly. Most guilds have ways for members to get in touch with each other outside the game - forums, facebook friends, texts - so there's no reason for a GL to get deposed unless they vanish. If something comes up, there are plenty of ways for a responsible GL to get in touch with his officers and let them know what's up before the 30 days have passed.

This feature is not for "oh my GL went on a long trip to Spain and we're using this as an excuse to get rid of him". This is for the "oh geez, the GL hasn't logged in to the guild in over a month and nobody knows what's up - rather than disband, let's get #2 into the top spot so we can keep on going".

I would set it up as 30 days to flag as inactive, another 15 days to actually remove. Some people have unexpected things pop up. I have many guild members that mysteriously disappear for weeks at a time. I don't boot them. Sure, GMs should be more responsible. In a perfect world, they would notify/promote someone trustworthy. I have some good officers in my guild but even they take breaks, some unannounced. What if you take a break and promote someone and they have something come up where they can't log on for 30 days? 30 days sounds like a long time to be away from WoW but it really isn't.
