I know more about WoW than you! Let me tell you some things. First: NPC is not same as pet. Players can have pet (Warlock and Hunter ... + minipets which don't attack, just cute) and those things you find out of cities are NPCs. Second: I was only lvl 7 PRIEST (ever heard of that: PRIESTS DON'T HAVE MANY LIFES) having less then half of mana and around half of lifes, when I attacked NPC (NOT PET!!!). I could easily beat it. That NPC had white name (means that, that NPC don't attack you until you attack it - if name is red it can attack you if you are to close). But then outta nowhere came another NPC with white name. How could I possibly know that it'll attack me? But that NPC attacked me. Then my friend told me that they were somethin' like father and son, so it attacked me, because I attacked his father/son. What could I do? They were both lvl 7. I just ran ... and heal my self. I didn't die.
And if you already asked ... I am using spells on keyboard.
Please don't talk about things you don't know enough N_T
BTW: Of course is not ofcourse but of course.
