At the very least I want to have both a male and female of each of the "Must Play" races and one of each profession (hmm, I suppose that makes all the professions "Must Play"...). Eight slots covers that. I could buy three more character slots for 800 gems each. If I buy those for real money, that's £25.50.
Or I could buy another standard copy of GW2 from Amazon for £34.00. For the equivalent additional price of just one further character slot, a second account would give me not four but five new characters, a second bank vault (worth 600 Gems, the cost of doubling bank space on an existing account) and the ability to mail items from anywhere in the world to characters that I own (otherwise unavailable at any cost).
Since storage space is a serious and pressing issue in GW2 (this blog isn't called Inventory Full for nothing) and since Mrs Bhagpuss and I are already mailing each other items to hold in mail-storage for each other because we can't mail to our own characters, the advantages of buying a second account rather than expanding the existing one seem overwhelming.
GW2 doesn't have an auto-follow command, so multi-boxing EQ2-style is out. It's also apparently not possible to log in two iterations of the client on the same PC. Technical issues aside, I'm nervous that doing either of those might constitute "botting" under ArenaNet's stringent interpretation of the concept so I wouldn't risk it even if there's a workaround. Logging in two accounts that I have bought and paid for, one on a laptop and the other on the desktop, however, seems to be entirely acceptable under the EULA, should I want to do so.
Are there any reasons in favor of expanding a single account that outweigh those benefits? I can't think of any. Chances are I will buy a second account, and sooner rather than later.
