Only thing I'd want in agi is handguns as the pistol can hit upwards of 60 damage with a good t6+mods before any perk/book damage bonuses. Int perks are mostly worthless to me, as are most perception and agility perks. Perception is for salvage ops 3 and lucky looter 3. Sledge/shotgun/sex t-rex/miner 69'er skills in str, fort is living off the land and healing factor 3 as well as some into mguns and probally heavy armor.
My basic build is 6-7 str (I use a cigar for +1 str and 10% barter if I find/craft one), 5 fort, 3 perception for a start. The goal is that by level 40 or 50 you have your basic build locked in it seems to me anyway. Maxing out a couple attributes seems almost ridiculously hard now. We hit level 40 something last night and exp has slowed to a crawl, a couple hundred zeds gave almost a level during horde night.
