Aight, so I finished my experiment.
I created a guild, invited some folks to it, to the point where the guild bank is unlocked.
And I wanted to see, what would happen if the bank is unlocked, and a member leaves afterwords, falling back below the ten member thresh hold???
Does the bank stay or does it go??? and if it does go, what happens to the items that were in the bank???
Well I now have answers to those questions.
When a member leaves, the bank is still there, but you lose the ability to deposit stuff in the bank, although you can still withdraw items thats in the bank, meaning they are still safe, if members decide to leave the guild.
I was wondering if it was like Final Fantasy 14 where the bank is still usable even if theres only one person in the guild. Looks that's not the case here. Thanks to the gaf member who helped.
I was going to do the same before but I found out about the guild bank locking again when I googled it. XD
Edit: Still stuck in queue. At this point I'll be happy if I can log in so I can steal 30 items to meet my fence quota of the day. :\
