Tal Rasha's Elements question

In reading the six piece bonus, it sounds like only the time stacks with each element. The 2000% damage doesn’t stack as well, correct?

Both stack. Once you get to 4 stacks, you can alternate 2 skills to keep the stacks going. If you feel like you need to get a full timer quickly though, you want to use another 1-2 skills to get the stacks up quick. Speaking of which, they need to fix how the passive works for the elemental exposure. It only shows a buff if you’re wearing tal’s set. It shows it nowhere at all if you’re not wearing it. Not on sheet dps or buffs.
