Macroing is in, it is permitted, nay-encouraged by the guild. There will always be a few people who dont do it, think its bad, etc. Most of the server will be macroing their collective arses off.

Most of the non-newbie macroing will require resources.

If you are unattented, that means anyone can come and take your stuff. That right there is more than enough to balance things out, its not like unattended macroing in DFO is without risk, excepting macroing the most basic beginner spells, ergo, is not and can not be game-breaking since it does not fall outside the risk/reward model.
