I am working on an elf favored soul, mainly for melee. I plan to go 18 fav soul/2 fighter. At level 1 I took toughness and Two Hand Fighting.

My stats are:
Str:16
Dex: 10
Con : 12
IQ: 10
Wis: 12
Chr: 16

My level ups will go to charisma. I will be casting mostly buff and protection spells.

Although I know I won't be a first rate DPS'er; what feats should I take to get the most out of it?

Is Arcane Archer worth taking Mental Toughness for?
Is Force of Personality useful considering the amount of charisma I'll have?
Would I be better off re-rolling as 18 fvs/ 2 pal?

Thanks in advance for your advice.
