I'm actually trying to improve the performance of my Tibia, so I made a question on Reddit (about another program not related to mouse macros to be used along with Tibia. It is a performance enhancer called "Razor Cortex") in order to get information with people that was active during the initial phases of Battle Eye implementation and what would be forbidden by Battle Eye. The Reddit user @XtrmJosh made a good point regarding it, where he says that any kind of unfair advantage (such as a macro that makes you use exura and a potion) would be a rule infringement, thus it would be punishable. Quoting what he said to me there: "...one keyboard or mouse event should result in one singular action..."
However, other users on the thread there alerted me that people are possibly circumventing it somehow and using complex macros to gain advantages during double xp/double skill weekend, but I can attest that macro users are possibly going against the interpretation of Tibia Rules. This is a rule infringement that may result in a permanent deletion of their characters in the future.
