Nostalrius Begins - Quality wow vanilla realm (1.12)

It is worth to get rank10 as warrior to get the pvp gear? Im just saying... untill patch 1.11, the blue pvp gear mostly give stamina, nothing more than that, it is worth?

Nope it's not worth it at all. However the reputation rewards going into 1.6/1.7 are very nice, especially the BiS leggings and you might incidentally reach rank 10 while grinding the rep.
