Guild Wars 2

I was wondering what ArenaNet’s policy on macros was? Obviously unattended macroing would be considered botting, and bannable, but what about simpler things? For example: What if you had a mouse that allowed macros (like the SteelSeries official Guild Wars 2 mouse, or one of the numerous Logitech gamer mice) and you set up a macro to act as if you were hitting 1, over and over again, so long as you hold down a button on the mouse; this would be to spam an attack that can’t be auto-attacked, like grenades, or perhaps to substitute for an auto-attack on the flamethrower which forgets to auto-attack when you switch out of it.

I would like a clear answer, please, as up until now the answers given on the subject have been very wishy-washy outside of disallowing obvious things that allow people to advance without actually playing.
