In my experience level does not dictate experience. You can get to 31 with vendor gear and you could get to 32 on normal Crota with little fuss with Cheesing. I hear lots of people saying "I saw this guy on youtube" but in practical terms have no idea. Bungee should never have let people buy level because in all practical terms you only need to be level 32 to do hard Crota. At least before TDB it was almost a given that if you were raiding with 30's there was a high chance they all knew what they were doing all be it at different skill levels. I would rather someone tell me they were not sure how to do something as I am more than happy to talk people through.
