Well the game is still keeping me hooked, the pursuit of loot is quite addictive. Now I've got items to regen my health and ammo it's a lot easier, although the problem with ammo regen is it removes the need to switch weapons to conserve it (meaning a bit less variety as I tend to stick with the same couple of guns 90% of the time).
A couple of annoyances:
-Increased magazine size seems flawed in that when you switch to a weapon often it isn't fully reloaded (has default capacity instead). It also causes problems with multishot weapons because if they normally fire a full mag, they don't anymore, meaning your second shot is much weaker (e.g. my triple rocket launcher now has ammo capacity 4, so it fires 3 rockets, and then 1 single one)
-The use key reloads if you don't have anything highligted, really annoying as it means I keep reloading when I don't want to (to be fair I haven't fully explored the options to see if this can be disabled yet)
-Quite a lot of backtracking, fast travel helps but even then the implementation is a bit flawed, often I can't recognise the name of the place I need to go to. It would be nice if on the fast travel screen it put some sort of icon to show which place is nearest to your current quest objective.
One question, with the DLC, does it matter what level you are (currently I've ignored it all while I am building up my character in case it is intended for high level chars who have completed the game).
