I don't see the appeal in this dlc at all. The combat in borderlands is okay, but definitely not the main drive of the game. What I (and most, I'm sure) enjoy the most about it is just running around scavenging for phatloots and developing your character.
Then this DLC clearly isn't for you. The devs were very specific saying that they developed Moxxi for teams to test themselves in arena battles, something many people were asking for. Dr. Zed is more about questing and loots.
I don't object at all to the DLC. I don't mind paying a little more to expand on a game I like as long as there's value in what they're offering and they don't saddle it with install limits. Why should I be bothered having to keep track of tools to uninstall my game? It's simply hassling the honest consumer. Also, they've priced these a bit high, imo. I paid a little over $30 for the game and these ring in at a third of the total price. I'd wager there's not a third more content.
