As you said earlier, you keep switching to monk. But get this, not everyone needs to like everything and that's great! This game offers different styles (and personally I can't stand the monk combat system) precisely because they are different. I for one like the ninja system because it is like it is. I duly hope they don't dump down each class to just be copies of each other with different skill names. If you find NIN system difficult for you, then just play something else. There's 4 melee damages to choose from, pick the one that suits best. Don't try to ruin other's favourites just because they don't suit you.
