Classic. Should get a Sticky.
One more suggestion: Remember this isn't real life. When ya die here, you're fine. Get used to die'ing. Embrace die'ing. Be one with your die'ing. Die'ing has no stat so embrace the conflict. More often than not, you'll figure out what you're doing wrong and suddenly stop die'ing.
As you said, dying is a great way to learn. Imagine if you played every Warzone to perfection. Yeah, it'd rock, but would you learn anything? Probably not, just ask most Frost Mages in WoW.
When you die, it's also not necessarily because of a teammates incompetence (though, it can be). Sometimes, the other guy is just better. There's always a bigger fish
in the world of PvP. As you grow, you'll eat them. Remember that.
