Yeah same thing happened to have crossed my mind too, about 2 weeks ago when this all started, it was almost like height had something to do with it as well. In some dungeons if mob was below me I could hit it, but it wasn't something I could duplicate. Sometimes it's 1 ft away and won't cast...other times it's "almost" full range, but never perfect (correct out of the box as it used to be). Can't imagine what they'll do to fix it but I've spent a lot of time on him and the stuff on him...would be bad if he or any of his things were misplaced...
