Guild vs. guild combat is important to the core of Albion Online, but it kind of falls apart if everyone is just grabbing everything worthwhile and then jumping ship at the drop of a hat. Thus, the latest update to the game going live on Wednesday will prevent you from joining another guild for 48 hours after joining one while also preventing guilds from changing their alliances within 48 hours. Leaving doesn’t incur a penalty, though, so there may be workarounds for those with chronic backstabbing disorder.
