Again - too many that I love to really choose a favorite. Some of these I've had, some I've just seen used, and others are only really fun because of who uses them. So here, in no particular order, are my favorite items in game.
I'll come right out and say it - I loved this weapon. Besides being a huge guild acievment, it was just an amazing weapon. I thought it looked great with my T2 and my ERB (still my favorite shield), and I used it until it was completely useless. I really regret making my warrior a Tauren now - so ugly.
This item isn't my favorite to use, but our Boomkin has a 22 slot bag full pretty much for every raid. There's something about seeing a mini-Boomkin just tearing it up that is pretty damn funny.
This might be one of those, favorite moments items instead, but I think fondly on jumping off AB or into the mine with my wonder twin Toby. It's tough to tell a Retadin and a Holy pally apart when they're both rocking the same looking gear and weapons. I don't know how many times carrying a two-hander has gotten me ignored while I just sit back and heal.
I may take the weekend off - so Monday will be day 06, a shot of my desk.
