Guild Wars 2

For the first level of the earth trait for the elementalist it says that toughness stacks for each level when attuned to earth, when I first unlocked it and switch to earth the little icon showed up showing the toughness being stacked. However, when I was playing in WvW the extra toughness when in earth never showed up.
Is it something that isn’t going to show up in WvW? Or did an update cause it to just not show up but in actuality the extra toughness is there?

And on a side note, the regeneration from the water trait line does show up when in water.

ok, when in the game, start in any other attunement and hit H -(Hero panel) Look at your toughness… Now switch to Earth, the green numbers (if any) should change. Same for Gain toughness while channeling a skill trait.
