I've added commenting on cards and scenarios at LotrLCG.com. The scenario pages also have some stats on how the deck is made up (% of enemy, location, ect) and some stats on what the average threat, defense, ect of enemy and location cards.
I hope to have card ratings done by tomorrow and you will be able to rate both the how difficult and fun a scenario is.
If there is anything else that you like to see, let me know!

good that you said this, cause then we can see that you are not to be taken seriously.
