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 made a second Hunter to grind raid gear but then I realized...I'm too lazy to do a raid twice. So I ened up using it as a second vault seeing as my vault was full of things (I find it hard to let things go. *Insert Let it go song*). I eventually deleted it to make a Warlock.
