Merging two existing accounts would be very convenient. Even just being able to add the CD key of one account to another account would solve many problems for me.
When I first bought my second account I ran into the problem of not actually having a second email address to register it on. I had to get another gmail sponser and maintain a useless email address. When I transfer things from one account to the next, I have to rely on in-game help, which I don't always have on hand. After all, my computer is the only one in the house that runs Guild Wars. My room mates aren't going to let me touch theirs, and one of them can't even run the game.
I don't really care about what I unlock because I'm just PvE, but honestly, what is the big deal with giving your unlocks to your other account. You earned it. It's no different from Having a high level character unlock all the necro skills on his secondary, then making a necro with those benefits, both characters on 1 standard account. How can one favor redundancy and have a problem with that?
It's not as if it isn't technically possible. My girlfriend happened upon a bug with her two accouts that shows they can do it.
Check it out. Why did they think 4 slots would be sufficient in the first place? I can understand the cost of server maintenance, but surely charging us for merging accounts can cover that. 4 slots for 6 classes and PvP only characters. Of course people are going to want a second account! Now Factions adds 2 slots and 2 classes, which is quite reasonable.
I don't care if they don't gain extra money from selling Factions to me twice (incidentally, they're not going to anyway). What about my f**king money?! In fact, if I purchase Factions twice, that's 4 extra slots on their servers, whereas if they simply merge my two existing accounts and make Factions work on it, they can just give me the normal 2 extra slots. They aren't even taking a loss!
I'm /signing this with a big fat marker.
