tested on: warlock with felguard
maybe it works with all pets, maybe not, im too lazy to test it now
i tested it with different mobs in icecrown, i don't know if it will work with all mobs
1. let your pet attack a mob
2. stop your pet from attacking and let it follow you
3. run to wherever you want
4. instead off resetting the mob will switch the target to attack you (if you run too far while the mob targets you it will reset)
5. let your pet hit the mob once, so the mob will switch it's target back to your pet
-> continue with step 2
