I know; I was arguing that way in earlier threads before the game came out. But I just don't notice that big a difference from agility. Maybe I'm missing something.
You need 7 agi to qualify for Slayer, or 6 with an implant.
SLAYER
ˉˉˉˉˉˉ
Level: 24
Ranks: 1
Usefulness: Unarmed Builds: [*****] / All-Round Builds: [**...]
Prerequisite: Unarmed: 90, Agility: 7
Description: Speed of all Unarmed and Melee Weapon attacks increased by +30%.
Again, this really shows how much the developers wanted people to
"like" Unarmed builds. It's a must for Unarmed builds, but not
more than decent for all-round builds.
the main thing about agility is that it raises action points in VATS.
AGILITY
ˉˉˉˉˉˉˉ
Agility increases your Action Points in V.A.T.S., and improves how fast you
draw, holster and reload your weapons, as well as your running speed.
You have 80 ap at 5 agi and getting 3 per point of agi, making 95 at 10.
