Oh thank god! I thought I was the only one who did this. I have had 27 deleted characters (some that I don't even get past level 2) and currently have 3 active ones. Started off with a Warlock, got to level 40 and deleted it because I hated the class. I now have 2 Hunters (just because Hunters, for me, are very easy to use) and a Titan. I'm considering getting rid of my lowest Hunter and just stick to two characters, don't know yet. I may keep it as a back up just in case I get better gear/weapons as rewards and move them to my main Hunter.
