Pets in World of Warcarft are pretty cool. There's little more comforting in the harsh world than knowing your frog (or cat, bunny, mechanical squirrel, whatever) is by your side. If it's not by your side, it is running to find and catch up with you. Pets are the most loyal companions you can have. And, yet, there is something lacking in their companionship, a trait that would be great to have in a pet whilst battling demonic forces bent on world domination.
I would like a new pet, one that shouts 'HOLY CRAP, TIGER! ADDS AT SIX O'CLOCK!' Personally, I think that would be a marvellous addition in a pet.
One friend remarked that he'd rather have it shout 'Thurgen' instead of 'Tiger', but I thought that was being a bit selfish of him.
Another had the brilliant idea of having the pet shout out only when there actually are adds behind you. I think this shows the merit of brainstorming ideas before implementing them.
