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've had 7 characters. Solo Hunter from launch to TDB, then a Titan, warlock until March when I started raiding. Deleted the T, W for 2 more hunters so I could just worry about one gear set. By mid April I deleted my 2nd, 3rd hunters for a Titan warlock again and been like that since, one of each.
