Didnt care to much about my pets name either.
But after lvling 2 "mains" to 70, got bored of them, and came back to my hunter, entered outlands, and seriously started to create a massive love for my hunter, I did pay attention to my pet and his/her name.
Before Outlands, I had my "tankaboar", the rare, black boar from Blasted Lands, and emediatly after I tamed her (dunno why I use her..) I thought she was SO sexy! She's as ugly as can be, which makes her sexy >.< So her name became: Zexy (coz Sexy isnt alowed)
When dinged 65, I went to Blade edge to tame the color-changing ravager.
Couldnt think of any name, so I left him with the name "Ravager".
After lvling him, gaining training points, and after I learned him cobra reflexes.. I was amazed with the attack speed. 1st thing which came up to me was a dual wielding Fury-Warrior. I'm from the Netherlands, So I gave Fury a Dutch "tint(?)" And called my Ravager: Fjoerie.
Still have no name for my Wind Serpent.. kinda hard to come up with a name..
Oh well, thats the story of my pets :p
