One thing I found in the expansion was that I routinely get gear three to five or more levels above me, which isn’t terribly fun, and then their are difficulty spikes which compared to the normal breeze-through difficulty on Veteran for many things makes the game feel really jerky, in a two steps forward, one step back way. I’m not sure the expansion stuff is that well balanced, and I still hate all forms of “turret” bad guys spewing whatever it is they spew.
