found a nice trick with the mob Lieutenant Dagel, standing about here in Orgrimmar.
Go to your Character tab, and hit At war with Argent dawn at the reputations tab.
Now you can attack the mob, and any other guy which is either hated with AD, or having the at war status with them can attack it. Great way to train DPS or weapon skills. Or just mess around cuz the sound gets annoying after a while
And another thing i found out, that if someone fears the mob in front of the AH, the mob will get behind the AH, and any random guy with a charge ability can charge in on the mob and get behind AH. There won’t be a los issue for charging behind there. But for casting, there is, on some places.
