Because everything is relatable to WOW and it’s so hard not thinking in Wow terms.
I don’t think someone has done this before, and it’s only because I killed the last boss in battle heart with a tank , under leveled minstrel, Mage, and cleric. So I had to find another game to play on the train and i rediscovered all these angry bird levels I never finished,and I’m writing this in bed on my iPhone, so please forgive me for my formatting.

Little red birds are your melee dps smacking themselves sofly against their targets.

I admit when I played Dragon Quest 9 I always had to make my party member icons correlate to their WoW counterpart class. Theif yellow, Ranger green etc etc… >_>
I was at the store wearing my Angry Birds shirt, this little 6 or 7 yr old kid came running up to me screaming..”OH MY GOD, you like angry birds too, their my favorite, never seen an adult like video games.” I asked him which one was his favorite bird, and we swapped stories.
It does my heart good when kids have the same love I did playing video games when I was that age.
A tshirt that’s cute. Do u have a plush bird? I am thinking about it. Can throw them cross the lounge room yelling weeeeeeeeeeeeee.
I would but girl playing with stuffed animals, not as socially unacceptable as a man doing it. I could do it behind closed doors, but that reserved for my high heels time. 😛
