Do you really need to be a single class Fighter, and if you can budge at all, what do you think is most important about being a Fighter?
"Need to", no. But I have a long-standing bias against multiclassing due to how it was pretty much mandatory in 3.5 and how most builds seem to dip more than a tobacco-chewing redneck tied to a fishing line.
Do you really need to use a Longbow? How about a Long Composite Bow or an Orc Hornbow? How do you feel about Thrown Weapons? How do you feel about other stuff like guns and magic wands?
How do you feel about Longsword? Why Longsword? Why not Split Blade Sword, Estoc, Greatsword, or Bastard Sword? How do you feel about Natural Attacks? How do you feel about Feats that let you use your Bow in melee?
I picked Longbow and Longsword specifically because they fit the thematic design of the bow and sword used in the Shadowshot and Daybreak skills. None of those other weapons fit the design very well (maybe greatsword).
For clarification, I'm not looking to optimize to Powergamer/PFS levels. I just want to be able to invest in the standard power-boosting feats while still having plenty left over to invest in feats that are more interesting than powerful, like the Weapon Mastery feats.
