Where FanaticMU stands on macros, plainly:

• Key-press macros are fine. A macro that presses keys in a sequence - a BK landing combos, a DL cycling skills - is allowed. Combos are meant to be used, and we would rather see them flying than gatekept by finger gymnastics.
• Potion macros are pointless. Potion use has a cooldown on this server, so spamming pots faster than a human does nothing - there is simply nothing for a pot macro to gain.
• The line is automation: pressing keys for you is fine; software that plays for you - beyond the built-in MU Helper - is not. See the Terms of Service.
