The build you see above is for Steel Essence farming by Bossman (their guide (Youtube))

The purpose for posting here is I'll provide a compatible build for a tanky general use Smeeta (here)

1) If just starting out with putting forma on your smeeta and you're interested in Steel Essence farming. Leave the polarity on [Sense Danger] by default, then swap out [Primed Pack Leader] for regular [Pack Leader] (so you don't have to forma that slot) and you have a 4 forma build. For Steel Essence farming you want [Fetch] Rank 0, so you can stack smeeta buffs while not picking up essence.

2) For more tankiness in general missions here's that build (again)
