Warrior Leveling

[Atima]

Looking to get my Warrior higher leveled. I'm currently lvl 46, and seem a bit disappointed with my dmg as of right now with a G.Axe. Here are a few questions/concerns:

Am I still supposed to be using Sturmwind at this level or should I be using one of the Break WSs?

Should I even be using a G.Axe or should I switch to /Nin or /Dnc and Dual Wield Axes?

Fighting Spiders in W.Altepa Desert I run with this setup:
Str: 57+14 without food
Base Att is 238
With Zerk+WC+Aggressor up and using Sturmwind
I do about 300-400+ dmg but not much higher, with the occasional 100 dmg while still getting a 15 pt Tp return, is this normal?

Will Keen Edge make a big difference in my dmg? I ask this because when I went through that same camp as my Drg and I got Penta-Thrust, my killing speed went up by a large margin, will Keen Edge do the same or should I switch to a different weapon?

Is there a different camp I should try at this level? I duo with a Level-Sync'd Whm, and we hit up the Fields of Valor pages for extra Exp and buffs.

What sub should I be using, /Thf for Sneak Attack?, /Sam for Store TP and then Hasso at 50?, /Nin for Dual Wield? /Drg for Jump for extra Tp/Dmg?

This post stems from feeling like I've hit a bit of a slump and I'm wondering if I'm just remembering wrong from my Drg going through this area (Pre Penta-Thrust) or am I doing the dmg I'm expected to? Thanks in advance for any responses.
