Stamina Gems?

[:1]I had a pally today in Zul'Gurub nerd rage because i had 4 stamina gems, should i switch them out to stam/mastery or just leave them as is?
Well it does not make you suck or anything, so I wouldn't say your "doing it wrong", sounds like that paladin needs to lay off whatever he is on, but in truth, the general consensus is that pure stamina is not the way to go, and mastery is considered superior.

Unless gemming to try to get a good socket bonus, in that case stam/mastery, all this assuming you have enough health of course.
