Nice that you are adding a couple of Mass spells, but instead of adding these wouldn't it be simpler to add a new metamagic feat called MASS that could be applied to a number of spells without the need to add new spells.
Also I think someone already suggested this but Spellsinger should get a MASS effect for their Inspiration Song - I don't care if it costs the same number of songs as there are party members to perform it.
Bank changes are welcome, but as Mikardo pointed out I think this is a sticking plaster that doesn't address the issues of Mules and BTC items. If I recall correctly Strimtom mentioned that one of the games he plays has a "Magic Items Manual" which logs the items you have looted and allows you to check them out from a trader, removing the need for a bank to a certain degree.
FVS need nerfing, but this seems excessive, so too with the Tiefling.
None of these changes should be introduced before the end of the current HCL. Put the update on the other servers by all means but the Hardcore server should remain loaded with the current build.
