Guild Wars 2

I wasn’t sure whether to put this in Tech Support or general, but here goes.
So, like a sensible gamer, I suck it up and play on Windows. However, I know several people on Linux (mostly Ubuntu or Debian) who are really interested in GW2 but won’t fork out the cash out of principal without native support.
With the arrival of SteamOS and such, is any Linux client in the works after the Mac one? Linux gamers are infamously generous when it comes to paying for optional extras once support is given to them, so it kind of makes sense from a business perspective.
Just curious; I can’t be the only person with people looking at the game, forlornly asking “Ubuntu Client?” and then mooching off to something like Eternal Lands in ugly, pixelated misery.

I understand completely that ArenaNet must be seen to be doing something about account security and such, and that making users change their passwords is a good way of doing this.
However, if one of their users has a memory problem (spoiler alert; I do) then forcing them to change the password on a regular basis to something within their guidelines, which are summed up pretty neatly here;
"Unavailable password. You or someone else has used it before, or it’s on a known list of passwords stolen from other games or websites. Please use a new, unique password for your Guild Wars 2 account. We recommend a new one made with four random, unrelated words, as shown in this comic strip. "
From this you can only assume that not only is it impossible to switch between several passwords that you can remember easily, but you also have to avoid the passwords of however many other users and their past passwords too.
That simply is insane. How long will any one of us be playing this game for? How often will this change be demanded? Every six months? Every six weeks? Even if it was every six years then there would be a period of at least a week in which I would have to be constantly having the password sent out if I ever learnt the new password. As for making a new password with four random, unrelated words well there’s a few I’ve yelled at the computer now that it’s finally stopped glitching through the new password demand, but I doubt they’d be original.
Simply put, security measures are good, alienating people because of a disability is illegal, at least where I live. I would be very grateful if the restrictions would be waved enough so that it is possible to cycle through passwords, even if it has to be not in a pattern or something. As long as it’s a password that I or someone else with this sort of problem can remember we should be allowed to keep it, rather that having kettlefrogpillowice or some such nonsense.
