How do you deal with Hex(es)?

Hexes such as Spiteful Sprit, and Rackless Haste, in the middle of a PvP, how do you remove them?

You call on vent/ts for your Monk to remove them. In RA, you just sit it out and don't attack. You can't counter everything and be effective at the same time, some things will always kill you.

Or with use of Holy Veil, Remove Hex..and so on.

I usually just wait it out, or ping it once if it's deady.

As an Assassin, Spiteful and Empathy don't bother me too much. I'm not attacking all the time. I'll find the target I want and attack through the hexes (as long as there aren't too many!) and usually I can get my kill before the hexes do too much damage to me.

I use Aura of Displacement so if the hexes do begin to hurt, or I get some people on me I'll just get out of there and wait until my Monk works his magic.

Wait it out. Assassins have the most impact right at the beginning of a fight anyway, the trick there is to get in and do your initial damage before your opponent thinks to hex you. In some ways the fact that assassins don't get much respect could be beneficial, as it makes it less likely that you'll be the first guy on the receiving end of a tough hex. And of course, if you get hexed right after you do that initial damage, you were going to fall back anyway to prepare for your next shadow step + dagger combo, so it's not like by waiting it out you'll be doing anything out of the ordinary. Since half of being an assassin is regening energy and placing yourself strategically, waiting out a hex isn't all that unusual to the play style.
