I don't I have the nerd comprehension levels, some of the same people who say this makes it too easy, are those who are telling everyone to get secret books at lvl 2 an 1/2 or that save is worthless, push stats to the limit, and work around on the really tough combats with "dumbed down" tactics.

Playing with a RL friend, I had gotten LW and GC, he disagreed but we did a battle. Without buying new stuff, working the char to max that build... We reloaded because the build was a little too good, we didn't even really discuss it, just both saw it was way OP and would probably dumb down the game. At that point the game was so good and fun for us, we didn't want to taint it. That spoke volumes to me.

Im still playing my first go through and I cannot imagine thinking this game was difficult enough to warrant min/max or purposefully playing 'cheat' builds.

For me and my buddy, the game was easier in Co-Op, not harder, so I gotta agree with the OP on this topic. If someone started justifying it instead of re-rolling, I would find a new co-op partner for sure.
