exhaustion questions

This is a "condition" correct? If so, how can i get rid of it? If not, why can't I get rid of it?

I believe every other condition can be removed, and as such I believe exhaustion should be able to be removed as well.

How do I ping that i have exhaustion (like i ping my health or energy level)?

Exhaustion can only be removed by zoning or waiting for it to recover (1 energy is recovered every 3 seconds).

I think if you could remove it, there would be a lot of broken builds in PVP =P

I don't think it counts as a condition in the same way as bleeding, etc. There's no simbal on your conditions/hexes/enchantments monitor, right? I think it's just unavoidable, once you put it on yourself. The only way to get rid of it is the natural way: just wait. You get 1 max energy back every 3 seconds, so every exhaustion you put on yourself is 30 seconds until you're back to normal.

It is avoidable, with Glyph of Energy (Elite):

Your next spell costs 20 less Energy to cast and does not cause exhaustion.
