The Defense Warrior in PvP

[Kevin]

The way I like to think of Last Stand is another healing potion the warrior can use. This is what it looks like to a healer too. The warrior who tanks for me swears by it, and says that it has saved us from a lot of bad pulls and unfortunate adds when the situation got dicey. Is that worth 3 talent points? It's up to the individual to decide.

Last stand has saved me and groups I'm in from wipes before. Just keep in mind that after the 20 seconds are up you lose all those HP. I've died from Last Stand wearing off a couple of times becuase I wasn't able to get the heal on me to get me up higher than the temp HP were keeping me.

I don't see the talent being all that helpful in 1v1 PvP, except to maybe try and wait out a heal pot timer or something similar. It has about the same usefulness in larger scale PvP when you have a healer around as it does in PvE. It's a marginal skill that can help at times when things go wrong.
