In the game guide the ability says "Your resistance to all elements is equal to your highest elemental resistance."
Which reads as, if across all my gear I have 400 all res and 200 fir res, my overall resistance to all elements will be 200, since fire res is my highest elemental res.
I assume the ability does not actually work this way or no one would use it. Am I correct that what it actually does is add the two together (all res on all gear + highest elemental res on all gear)?
If so, fail description of the ability by Blizzard.
