So ive started a second avatar, a melee this time.
Ive gotten Banzai, and wanted to go for the improved armor to culminate in "lol @ spears" obviously.

Now i have spent 1 point in melee defense, and since ive unlocked Banzaii i most certainly have spent 5 in melee combat.
But it doesnt let me unlock improved armor.

Anyone else had this?
Is the tooltip worng on this one? Do i need more than 1 point in defense?
Do i need morale, although it doesnt say so?
