So my friends just bought this game and I wanted to play with them. So I started fresh and made a new character and beat the campaign and all that fun stuff. After this though we decided that we were all going to buy the DLC, just after everyone became raid ready for the Leviathan raid. I purchased the DLC thinking that I would be able to halt my progression and have the choice to continue past level 20. But now I'm getting engram drops that are almost 300 on my level 20 titan at power level 200. I was wondering if there was any way to stop my progression or if I'm just screwed.
