When Blizzard made this button, did they consider what’s happening if a hunter looses his/her pet in the middle of a fight? It took me a few seconds before I got what the whistling was all about. I have no idea why my pet didn’t turn up, but it didn’t and I was nearly killed because I didn’t do anything but whistle.
PS
And please, let us edit this button with what spells we want in it. Both my DK (frost) and my Mage (frost) are on suicide missions when using that button, as many of their spells are AOE, which might not be the smartest thing to use in all situations.
