Dude its not an exploit. It's called dedication. The in game story is really annoying and repetitive the 5th time through. I am leveling my 5th character. I had 2 hunters and a titan but removed the second hunter for a warlock. Now that my titan is maxed I deleted it as I don't like the playstyle of the class. I'm now leveling a hunter and I'm just looking to get to 20 fast.
