Guild Wars 2

What will happen when these traits meet?
• Earth: Stone heart – You cannot be critically hit while attuned to earth
• Strength: Burst Precision – Burst skills have an increased chance to critically hit ( Chance: 100%)

How/Will these cancel each other out?

After it happened the first time, I kept an eye out each time to make sure.
Has happened a few times now where I’m positive I’ve damaged things.
(For example this morning, in wvwvw while in vapour form – loot even dropped beside me, yet no rally)
Plus I play staff, so I do definitely tag things haha

Is it possible to rally while in Vapour form?
While in Vapour form I am locked out of rallying when an enemy is killed.
Seems strange that a downed ability would stop this.
Can anyone shed some light on this please
