Amazingly enough, there are still many new players coming into the game that need some tutoring. I consider myself to be downright patient. If someone asks for help or advice, I'm there. If I don't have the answer, I point them to one of the many WoW resources that will assist them. At one point in time we were all rookies, and many of us still have many nuances of the game to pick up. I love to watch people learn and grow.
Bear in mind that WoW has a variable learning curve based on familiarity with MMORPGs, time spent playing, coaches, and aptitude. There comes a time though, when folks should be pretty self-sufficient. The argument "I'm new" no longer holds water. For example, it goes without saying that hunters should always check their ammo supplies before going into instances and in general, clothies should let the tank pull.
