I find that cloth armor works good enough at T6 to cover most needs and I mainly play melee. You can loot that pretty easily as you level. So until I start seeing Q6 iron armour I have no need to invest anything into armour skills.
Then really it depends. I like to do
Level 1: Advanced Engineering 1, Miner 69er 1, Sexual Tyrannosaurus 1, Animal Tracker 1
Level 2: Master Chef 1
Level 3: STR 2
Level 4: STR 3
Level 5: Sexual Tyrannosaurus 2
Level 6: Miner 69er 2
Level 7: Pummel Pete 1
Level 8: Healing Factor 1
Level 9: Living Off The Land 1
Level 10: FOR 2
Level 11: FOR 3
Level 12: FOR 4
Level 13: Living Off The Land 2
Level 14: Pain Toleramce 1
Level 15: INT 2
Level 16: INT 3
Level 17: INT 4
Level 18: Advanced Engineering 2
Level 19: Grease Monkey 1
Level 20: Rule 1: Cardio 1
So first 20 levels I look to get faster breakage of stuff, better iron tools and then a vehicle plus natural resist and crafting better stuff. I find less need to put points into weapon and armour skills right away but the pummel pete for baseball bats.
