Word just in from the test realm: tabs 5 and 6 of the guild bank have now been discounted, down to 2,500g for tab 5 and 5,000g for tab 6. Still fiendishly expensive, but marginally more attractive now.

Still not attractive enough to make it worth spending 7 – 8,000 gold for the last two or three bank tabs, when you consider:

• a bank alt with 14-slot bags in their inventory and no bank bags has 96 slots (at the cost of about 10-15g in bags)
• a bank alt with all bank bag slots purchased and full 18-slot bags in the bank and inventory has 238 slots (at the cost of 111.1 gold in bank bag slots and about 400-500 gold in bags)

So, you can replicate tabs 4-6 of your guild (cost: 8,500 gold) with two alts (cost: about 550-620g). When you consider that my last post on the issue shows that the guild bank interface is an awful way of accessing some kinds of stored items anyway, I really doubt that many guilds will be forking out the cash for those last three tabs.

Edit: it seems this iteration of the patch increases the costs for the first three tabs, while making the later tabs cheaper. It’s now 100g, 250g, 500g, 1000g, 2500g, 5000g.
