question about salvaging 70+ rare
I think you need higher level stuff to get ectos. They are somewhat random.
You got unlucky, unfortunately. To my knowledge, rares level 70+ can give 0 to 3 ecto when salvaged, weighted toward the 0 end. You can use master kits, your luck will turn around. Otherwise, complete daily reward, they have a small chance to give you a black lion kit.

Level 68+, not 70.
And as far as I know the tier of salvage kits does not matter, people have gotten globs by salvaging with the most basic kit that has 0% chance on rarer materials. The rare materials chance only affect upgrades to t6 mats like ori and ancient wood.
