Here is the simple way to get all 70's resists on a suit and still have room for good mods. It took me a while to learn how to do this since no one wants to share their secrets with other crafters lol.
All you need is a salvage bag, and all the colored leathers so you can pick through them t get the resists you want. My personal preference for armor crafting is barbed leather, unless i am making a sampi suit without reforging or enhancing to get the fire resists high (the cheapest way for an order on a poor person).
When you are crafting a suit for you or someone else, the best thing to do before the imbuing process is to get at least 3 70's in your resists. I have found through my years of crafting that it is not easy to get that on physical resist, so it is better to imbue that resist up.
Energy is the easiest to get to 70 before imbue, so i always try to get cold poison and energy to my 70's that way you will have only a few pieces to imbue the resists on so you have all the extra weight for nice mods. Pretty simple once you hear how it's done. ;)
i know this isn't an uber thing to have a post on, but hey, it took me a while to figure that part out on my own and kept getting frustrated when i would make a suit and have to imbue a lot of resists and had no room for the mods i wanted.
I hope this helps someone out as it will make your suit crafting much easier and like i said, saves room for the mods.
Never forget to PoF before imbue =)
