Nail on head Quad, at that stage of character development you should be choosing an offensive stat. I've been RPing and dumping everything into faith for my lightning tank. He looks cool and those bolts take almost every enemy out in one hit. Once he's our of bolts though he's on for a very tough time.
What fanboysuck said to be honest.
Also, how are you using the grant with only 12 str? Or are you not using that.
Either way, with those stats you can easily switch to dex as you haven't pumped str that much
