leveling up my hunter

[IgnisCaelum]

I am going from level 4 to 5. Any recommendations for optimising her?
I have a wolf companion.
Current feats are:
Combat expertise
Outflank
Combat reflexes
Pack flanking

I am aiming for a flanking build, I use a silver dwarven longhammer with lead blades on it.
I use iron skin on myself.

What feats and spells should I take this level? We are in a undead campaign so I'm mostly fighting evil things.
Someone mentioned a brawler multiclass at one point but I can't remember what it was, or why I should do it.

Brawler does open up some interesting things. Hunters already have the ability to swap out teamwork feats as a standard action. With a brawler's martial flexibility, you can now grab a second feat. Having 2 movable feats gives some interesting options. Combos that would be passed over for being too situational, become viable options.
