I noticed exactly what your talking about in EoTS,WSG,AB, etc before I even started multi boxing, If there is a multi boxer in the BG every moron in the BG wants to follow the boxer around. They will constantly be up your a$$ and will not complete any objectives. Unfortunately the IQ base in wow for alot of its players especially the younger ones isn't very high. And yes they will try and blame you even though they were the dummies following you around instead of actually playing. Theres nothing you can really do, you can try and spam a macro at the beginning of the match to not follow you and actually play, but I doubt it will help
