Since we're locked to 1 character, now capable of having a profession AND a combat role... I really think we need more bank space. Me and a friend were discussing it and really there is just not enough bankspace for 2-3 combat kits, reagents and all the profession stuff that we all do.
So... we thought wouldn't it be great if we could just buy more bank tabs, like you could in other games (gloria victis, WoW, etc).
Perhaps even SV can get a cut of this... the first 4 bank slots (adequate bank space already) could be purchased with in-game currency perhaps starting at 1 gold, 10 gold, 100g, 200g.
If you can't get your hands on that much gold... then perhaps you could pray to SV and "donate" some monies (2-3£) per slot up to a max of 4. These slots would be like normal slots, but unlocked in all AI cities (that would suck if you bought them and had them only in Fab).
