Barbarian lvl 50 class power broken
I finally got my ME barbarian to lvl 50 so I could true berserk while dual wielding whips and my energy cost went from 1200 (had 99 dx) to 2800. I then unequiped 1 whip to test it out and instead of having 595 e.c. I had 1395.
My conclusion is that somehow when you get the lvl ability, it adds 800 cost per weapon, instead of giving a 20% discount as it should.
