Regarding Bank Guilds
Yes, the olf personal banks were grandfathered into the the new switch and nothing is required to continue the use.
New guilds now have influence which can be converted to various uses at huge cost, but no longer obtained unless you have old scrolls of influence sitting about. They also use Atherium which is a time gated currency that can be adjusted to hold more and build up faster through various mine upgrades, and favor which is received via completing guild missions. The amount revived varies based on difficulty of mission and on randomness bonus or not.
I don’t think the private guild storage is something that is worth the extra storage now. If you are just trying to xfer goods, then the mail system sucks for that.
On that note, I wonder how much some one would e willing to pay for a personal guild with full storage unlocked. (Purely theory, not willing to sell.)
They sell it already, see allmost daily that someone offer or search a guildbank.
The price for 250 slots is about 250 and 350 gold. Would never sell mine for that price….
Interesting I never seen any one looking yet, but I agree, not even close to the value.
