Yes, I know tanking trinkets change based on fight, etc. I'm looking at general-use.
I'm almost considering H Lei Shen's Final Orders? The other two choices (Ji-Kun's/Fortitude) don't seem as appealing; the base stats on those two are nice, but the proc on Ji-Kun's isn't that good and Fortitude's on:use isn't that great either.
Darkmist Vortex has a really long ICD so I'm just ignoring that for now.
Last note, I am looking strictly at normal mode ToT trinkets. Once I get a chance at H Ji-Kun's or Fortitude, I'd definitely use them over H Lei Shen's. While I'm looking at the normal versions though, it seems like H Lei Shen's could be better.
