I'm going to get the DLC for the 360 when that comes out, but I don't know if I should continue my lv 111 character or start a new character. My thinking on this choice comes from wanting the new content to feel as challenging as the first run through of the game. The problem is that I've logged over 330 hours and I'm too experienced to feel overwhelmed by stuff like I was in the very beginning.
If I go to the DLC with my current character I'll have access to every item in the game with a reserve of 30 million+ souls that I've gathered from over 150 hours of PVP. All my equipment is maxed and the only downside is that my stats/level were buffed to deal with some of the NG++ bosses so I have points that were put into attunement, faith, intelligence, and strength instead of other stats. The hope would be that the enemies and bosses would receive a nice enough buff from the NG++ that I would feel challenged.
The other option is to start a new character and get to the DCL area as fast as I can. The result would be weaker weapons, weaker armor, and no access to items that could really help in a pinch. I also wouldn't have the stamina and vitality to play the way I play with my current character and my soul bank would be gone so I couldn't simply buy up all the stuff I need. The con is that the enemies would be at a normal game level and I don't even remember what its like to fight them in such a weak state.
What I wont do is purposely weaken myself by not using the best weapons and armor available to me or trying some kind of no healing run. I'm sure everyone else is deciding on doing it with a new weaker character or their current main so I'd like some input on this.
