Agreed, I have found my self just rage questing just so I can level up as fast as I can. If you find yourself dying alot, most likely
1. You may have bad gear at which you need to update.
2. You don't have a balanced group of healers for the heroics (e.g. healer/tank/dps)
Always be sure your gear level matches ~3 levels with your character level. If you're low level, try investing on stims for your character. Having that added endurance or strength on your character really makes a difference.
