See my comment about Bilbo and the trolls above.
Bilbo actually DID things in The Hobbit in addition to just making a crapton of stealth rolls successfully. He fast talked trolls, straight-up fought some spiders, fast talked Gollum, fast talked dragons (apparently hugely powerful beings in Middle Earth are very vulnerable to fast talking).
Frodo, on the other hand, pretty much does NOTHING in LotR except make a crapton of stealth rolls, walk a LOT, and fails a very important final will save at the end of the campaign. The amount of times he is saved by a Mary Sue NPC to advance the plot and keep him alive is humorous....
