Weapon Group Focus

WEAPON GROUP FOCUS [General]
Select one weapon group which you are proficient with.

Prerequisite: Weapon proficiency (selected weapon group), character level 1st.

Benefit: You gain a +1 bonus to attack and damage rolls you make with weapons from the selected weapon group.

Special: This feat can be taken multiple times; its effects can stack or apply to a new weapon. Each time it is taken, its character level prerequisite increases by 5 for the purposes of stacking but not for selecting a new weapon group.

Comments
The original Weapon Focus feat is hardly beneficial and overlyfocused. A character wielding a bastard sword and trading it for a broad sword could lose the benefits of their years of swordsmanship training. A better use of this feat would be to add to both attack and damage as well as use the Weapon Groups variant from Unearthed Arcana.
