I don't agree with this, I enjoy the progressive difficulty of the fights, it keeps people from beating it too quickly. Some might get frustrated by wiping I suppose but personally I enjoy it as long as I'm seeing progression. Nael just wouldn't be as much of a badass if he wasn't so hard to beat.

To me it seems like what you're asking for is a lack of mechanics, the only way you can ensure a fight doesn't become progressively more difficult is to reduce the number of them taking place.

I hate the nerfs to fights in this game and don't want it to get easier because it takes some of the fun out of it for me. At the end of the day they tend to make everything easier anyways.
