@gariondavey I've once tried this set long long time ago, and on medium too. Several issues here: duration is very low for something as essential. HP% boost is also only on one bar.
This build doesn't stack SD, neither I need stam sustain, so medium would be mostly wasted. Heavy armor passives are actually really nice here - 30k HP is 64 in magica and tristat food. Medium, it would be at least 3-4k lower. Healing received too.
@gariondavey go for tripple magrecovery. I find myself out of mag more often than out of stam. Besides, high elf has sustain passive that will give you resource you lack more.
