Actually, armor pen against cloth isn't that bad. I did some quick math on targets with about 6000 armor and if you gemmed/geared for all strength you would do about the same damage, if not somewhat less, than you would as if you gemmed all armor pen. I think this is because of the higher amount of armor at 80 than at 70. At 70, this was definitely not the case. When i switched from all str gear/gems to armor pen, I lost ~70 top end damage, so that is the difference in pre-mitigation damage that I used. If you want to see some math here it is:
6000 armor = 28.25% mitigation
with 10% armor pen from stance, 6000(.9) = 5400 armor = 26.62% mitigation
If a damaging attack does 1850 before mitigation:
1850(1-.2662) = 1850(.7338) = 1357.5 damage.
With 10% armor pen from stance + 25% from items (35% passive total):
6000(.65) = 3900 = 20.38% mitigation.
Damaging attack does ~70 damage less than before, 1780 damage before mitigation:
1780(1-.2038) = 1780(.7962) = 1417.2
As you can see, the damage actually went up, not down. Your grim toll procs will increase this damage more, but not the 44% or so that it would on plate.
Of course this doesnt take into account the survivability I lost, which was around 500 health and 150 resilience.
