1. @BluceRee - If you follow original build, you put excess points into vitality, and potentially respec to full str at the end of charm progression. But first you put 250-300 in str to equip gear, and rest vit, including signets. Guide is meant to show progression without specifically farming signets, so they are low priority, you don't actively farm them like with for example blocksin to get dex for block, which is sometimes almost mandatory, and makes big difference in character performance.
2. @Matata - Build is about going with what you find, nothing there requires farming, tiered uniques are easy to make. You are meant to craft axe with random shrines that drop during your progression. if you don't get anything good, keep using tiered unique axe, its good. Basic crafts for armor slots, really take few shrines to get, so farming shouldn't be required. Easy place to get shrines would be k3ba uber, kurast. You will spend there time to get 5 levels at one point, and during that period you should find decent amount of shrines.
Sacred uniques tend to drop most in duncraig, so that is another later stage where you should have fair chance of finding something usable. But as I said idea of the guide is to make it work without any specific hard to get drop only items.
