I have to agree. Making the Winterbane and Pagoda dungeons "No Trade" is complete bull. It also serves no purpose. No one is going to buy them for multiple wizards and all the items you can get are tradeable anyways. KI just made it so you can't have fun on more than one school.
I understand that the houses can't fit into the little bank in your house, because of the whole, house inside of a house scenereo....
However, the Pagoda gauntlet fits in my attick, so it "Should" fit in my bank.
How I solved the issue for myself.... 1 - I created a house with ONLY the Pagoda in it 2 - I put it up on Castle tours 3 - I get my friend, or my alternate account to visit(You can use the Pagoda during castle tours by the way, my wife and daughter use mine while I'm working, I don't know about Winterbane, as I've yet to get it) 4 - I jump to said friend or second account, and enter the gauntlet.
That all being said, i still would rather just be able to shared bank it and let my lower character have it.
