It's 100% of the time when others lag you.

That being said, depending on the situation it might not always be particularly helpful to you depending on the specifics of the lags, when in the round cycle it happens, what you're doing, what else is happening to you, etc.

And really, that's true of most things in the game -- stone skin is almost always damage reduction, but that's not helpful if you're getting hit for 100 when you have 10 HP.

Yup.

I think probably not, but it doesn't really play to any of the somewhat odd ways I tend to play the warrior class -- not that it's exactly a bad choice for anyone, but I usually have some kind of scheme in mind that calls for two legacies (not always offensive ones, but not usually that) that aren't Harmonius. That's a little ironic because it actually would be the ideal legacy in some pretty common situations I die in, but it's just not flashy enough for me to really want.

That being said, I've seen other people take it and make it look really good, just as they do with some of the specialization options in the game that I don't do great with.
