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 deleted 4 characters At first I made one of each class Hunter, Warlock and Titan I quickly learnt I enjoyed playing my Hunter a lot more then the other two so made three Hunters. I then learnt burning through content is pointless so deleted two Hunters. Now I just play on one Hunter and think it's the best way to play in my opinion.
