I know I am late to the party but damn Borderlands 2 is fun. I love melting those psychos with my acid elemental guns. The only complaint I have so far is the lack of easy travel point I hate having to slog back through areas and kill everything before I can get to my quest area. Last night I had one where I had to go through an area I had already cleared and everything respawned including the boss and then did my quest and had to go back through the area I had already cleared of ammo boxes and fight everything again. If the enemies are there the loot boxes should respawn also in my mind.
