Yeah, I didn't MIND the Den Defence but i didn't enjoy it or really look forward to it, but I found that also served to make me a more cautious player. To be honest, that's what I loved about this game. People have always been complaining that the AC was too easy, and now instead of simply adding a difficulty setting where enemies can do more damage or you can get less health, there are all these great systems in place that create difficulty. If you want things to go smoothly and be able to walk freely, then you need to be constantly aware of bribing officials etc. You have to move through the city like an assassin would, hiding in plain sight. I used blending with groups more than I EVER did in the other games and I found the experience all the more rewarding for it. It's the same reason I like the 100% sync challenges on each mission. Sure I could just run through and kill everyone, but going for the challenge makes me feel more like a Master Assassin. I loved the challenge in this game.
