Both setups are very bad tbh.
But if I was forced to pick one I’d go with the first one.
You don’t need mf for countess, you farm keys and runes
You don’t need mf for cows, you farm bases, crafting supplies, runes and charms
You don’t really need mf for chaos, you do the seal pop trick and you get all drops from 0% mf anyway
Mf can make sense in the other areas you listed, IF it’s early ladder. Those setups really don’t make sense for end game where the value of all the common sets/uniques you’ll drop from increased mf is turned to shit. Density destroying TZs on high player count should be your goal for end game. That’s when you drop your mf to around 100-135% and you aim for fast clear speed on p8.
So you’d be looking to either respect to something else than blizz… or to build a high dmg blizzOrb setup with either Doom or DF
The TAL MF on the blizz is just meh! I am running voice of reason and clearing much faster until I get a doom. got to clear fast and furious 8)
if i get a hold of doom would i still need cold sunder? would be nice of a build that can avoid that
