Guild Wars 2

Your skills on land are different than underwater. Some skills cannot be used underwater at all. You can set them above and below water, and the bar remembers which skills you had in either state.

The traits do not do this at all.

So, as it is now: if you use different skills underwater (which is likely), then you should re-assign your traits every time you go under. This is tedious, and without it (depending on the builds / skills / traits / weapons in question), I am effectively less effective just because I went underwater.

Traits should autoswap just like skills do when going underwater. For example, as a Guardian I cannot use 2 of my 3 class elites underwater. If I trait into a tome, to extend the duration of it, that trait is useless underwater since I cannot use the skills it pertains to.

Thoughts? Other examples?
