There should be NO MACROS in game period,whether attended or unattended.This just opens up way too many problems and security issues etc.
The only way that macros which shouldnt be allowed anyway if they were allowed would be to allow open PVP then so that a pitiful lazy macro'r thats hogging an ore field or particular mob that drops rare items could be blown up thus ending they're monopoly on the area.
I know this wont happen but if they were allowed to macro this seems the only fair trade off for other players who actually PLAY the game.Im sure Ill get flamed but my Nomex suit can take it.
