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]

None. I don't know why people delete characters as much as I'm seeing here. I have one each. More than one seems stupid to me, besides gaining more gear quicker from raids. Which still seems bit iffy to me since that's just basically one extra chance on a chest or boots that might suck
