Questions about Raw Build / Bluemoon Greatsword

I'm working on a Raw build that's going to main the Bluemoon Greatsword for mid level (SL 80ish) PvP and have a couple questions. My current Str/Dex is 15/10 (15 for the Old Knight Hammer) and I don't want to add any more points to that than necessary.

  1. Are there any good fast weapons that benefit from the raw infusion and that would require a minimal amount of investing further into Str or Dex? For example, santiers spear is out. If not, any fast weapons that are particularly great with another infusion but that don't require any more stat investment? No rapiers please

  2. Is the 1H move set of the Bluemoon Greatsword worth investing 14 more points in strength? I could really use those points in other attributes like Vigor or Endurance but it would be nice to have more variety.

Thanks for any suggestions!

Edit: I appreciate everyone's suggestions. Very helpful. As to question 2: after running some numbers, At 30 Str (again for the old knight hammer), the Bluemoon Greatsword infused with raw still has superior damage to any other Greatsword (at least counting physical damage) probably because scaling is relatively minimal in this game. Thanks again for everyone's thoughts.
