Finished the main campaign with my second character (Vex, with the "pet" skill tree), this time in hard mode (first time was normal mode). Yeah it got harder but by this point you've already developed combat strategies and you know the "tricks" of how to beat the major bosses, so it wasn't too bad. Now I'm experimenting with the "ultimate vault hunter" modes which isn't just like new game+, there's a bit more to it than that. I've never really bothered with this "end game" stuff wih Borderlands, and not sure that I care to take it too far - just got to UVH2 mode, and it was challenging. I don't want this to turn into a slog that just pisses me off... will probably play something else for a bit and then start over with another character (probably Amon). Now they're talking about a 5th character coming out in DLC sometime next year.
