Guild Wars 2

Are these legal to use in GW2? What about macro keys that I might assign?

I have a medical condition with my hands and I find jumping almost impossible for me to do, making my maps impossible to complete. Storing macros for jump and other tasks would help me a lot, but I do not wish to get banned for using one. Has there been any official response from Anet about these keyboards?
I am looking (possibly) at the Mad Catz S.T.R.I.K.E. 7 gaming keyboard.

Can you use the keyboard: Of course.

Is using macros against the rules: Yes. They have stated that they are okay with simple things (Basically rebinds to “I press one key, I do one thing.”) However, what you’re suggesting using them for basically, ‘Remember this sequence of jumps’ goes outside of what they’ve stated they’re okay with, as it automates parts of the game (like a bot.)

Will you be banned? Probably not. Tracking macro use is next to impossible, especially for infrequent macros to do mundane tasks that a normal player would be doing anyway. But it is against the rules, and could theoretically get you banned if A.Net caught you.
