He does well on bosses, he beats most on his first or second try, but he struggles with almost every random enemy and every bit of moving through every environment. His build has enough faith to do miracles, enough strength to do heavy weapons, enough intelligence to do magic, enough dex to do dex shit but no health or endurance. He tries using all of these things at the same time, but is spread so thin he's complete shit at all of them. The only reason he's gotten most of the way through the game is that he has a lightning zweihander, which is fucking unstoppable against most enemies and does great damage to most bosses.
He just wants single things from each thing. He spent like 19 levels on Faith so he could use Homeward. That was his whole reason for doing it.
