It's been seen time and time again, legion rosters full of members...Who haven't logged on in months.
How this will be handled in DoY: If you are planning on being gone a few days, just let a Councilor know as a heads up, or post it here on the forums. Life happens, we need breaks, got a new game, etc. Not a problem at all, just let us know so we don't think you disappeared into thin air!
That being said... If you are inactive for a month or more, without forewarning, you will kicked from the legion. Nothing against anyone, it's just not a morality booster seeing a list full of inactive members. If you happen to come back and find you have been kicked out, just shoot us a message and we will happily accept you back!
Throwing caution to the wind with foolish ignorance. You're full of pride and arrogance, You can't accept the nearing end of this short lived life.
