Usually, you will see people swinging towards the AP one.
For most warriors, you will be able to hit 12k hp pretty easily unbuffed in full pvp gear and certain enchants. Also, with the high amount of armor we have, it makes physical attacks do that much less damage to us as well. Not to mention second wind, which makes staying up a lot easier... These are also probably the main reasons you see people socketing STR gems instead of resilience/stam gems in their gear compared to other classes. We already have enough survivability, just kill that ***** ASAP!
