I deleted my male warlock in vanilla because I wanted to make a Titan and I deleted my male Hunter to get a good looking cloak in HoW
[spoiler]no, I didn't deleted my Hunter for stats.[/spoiler]

I had a Hunter at the beginning as an Alt, but at the time, I didn't like Hunters so I deleted it so I could have a second Warlock to get my characters to 32. Then I decided to give the hunter another chance before HoW came out so I deleted my second Warlock.
