How is damage calculated when guarding a team mate in PvP?

[Deleted]

When I'm guarding a team mate in PvP is the damage calculated;

i) Guarded target is hit by an attack, targets damage reductions are applied, the resulting damage is split equally between target and me.
ii) Guarded target is hit by an attack, damage is split equally between target and me, individual damage reductions are applied.

Thanks for any input.

I'd imagine the first, but even in the most extreme circumstances, like a 4 point Shockwave Smash on a Sorcerer, the difference between the 2 would only be a few hundred points. It could be the difference between life and death, of course, but probably not.
