Bowazon decisions decisions

Focusing more on my Bowazon finally since the pally just kinda needs a little gear tinkering (yeah Im slow I know I don't play 6 hrs a day) I started to build it with a freezing arrow, GA, pierce and a pt into everything else in the passives pretty much. But I decided for what I'll be doing with it, freezing arrow isnt going to do anything for me since I'll always have the level 20 magic arrow to fall back on for immunes from the WWS if I was that desparate. So....I restarted and rebuilt. Level 25 now with no skill points spent where do you think I should put the points?

Right now I'm thinking:

Bow Tree
MA: 1 (prereq)
MS: 1 (prereq)
CA: 1 (prereq)
GA: 20

Passive Tree:

CS: 1 (useless with the DS on WWS...Im pretty sure it wont check for this if DS works)

Penetrate: 1
Pierce: 9 or 20 if I use razortail or verdungos or nos
Dodge: 1
Avoid: 1
Evade: 1
Inner Sight: 1
Slow Missles: 1
Valkyrie: 1

Even if I use 20 into pierce which I probably will as razortail isnt that great outside of the pierce, thats only 51 skill points used. So...I'm going to have like 45 skill points to use still. I know I probably should throw a few more into D/A/E for defense but I'm not quite sure what else I should be doing...I could boost the valkyrie maybe or up CS for a secondary bow...or penetrate just for more AR?...But my dex will already be above 300...I suppose I could throw in a couple points in the jav tree for a jav switch in cows or something but it seems like such a waste.
