Pretend you start as a Faith Build in NG, you'll want access to Pyromancies, Dark and a few Sorceries in addition to your Miracles. With higher tier Sorcery you still have to your Intell requirements and you misout on Dual Scaling with the Rank 2 Staff. Heck, Golden Ritual Spear does the same job, is a weapon with Faith scaling Magic damage. Basically I'm saying this is a waste to get in NG and pointless beyond completionist after NG+. Rank 1 in Aldrich Faithful does at least have a point. Your call, just have fun either way because your Faith build will need Rank 2 in Sunbro no matter what.
