ah ok good points, will revise my build.If you are good at dodging and reading enemy "tells" then you don't need a shield. Shields are used to either make defense easier (timing is less critical and stamina management more important) or to vastly increase your DPS by parrying (bucklers, fists, and some light weapons though there are exceptions). Although some shields in the game are quite nice to have equipped but never used as they provide passive bonuses like stamina regen, bonus amount of souls dropped, etc.
As mentioned in the post before mine, upgrading weapons is much more efficient for DPS than upgrading your level (A +5 weapon does vastly more damage than a +1, for example, and a +9 significantly more than a +5) . Stats are important but for reasons that are mostly indirectly related to damage (though if your weapon has A or S stat scaling, it can still be significant). Things like meeting weapon minimum requirements, having enough encumbrance to wear the vanity armor you want to wear, a level of stamina that you're comfortable with, etc.

Titanite scale is like impossible to find. I haven't been able to upgrade these boss weapons. I'm guessing standard weapons like longsword is easy to get to +5
