Hunter already said the ONLY things you can use MQ2 for is Map and /stick.
That is all.
Ghost targeting and stuff to send in a pet or anything to that effect will get you banned.
Reviving an ancient thread, I know, but just for clarification: since in fact you don't need MQ2 or any add-on at all to use /target , is it a bannable offense to use it when the target is behind a wall?
