I'd imagine it's more that someone who is l30 or lower by this point is either really new, just started an alt, or doesn't really play that much... 2 out of 3 will increase the challenge, and despite what ppl on this forum say, they don't want a challenge, they just want a cake walk and loot.... In reality if you can't carry at least 1 noob/lower level you aren't that great...
