Instance Drops And Such

Is there any website, similar to thottbot for WoW (forgive me for speaking its name!) that lay out the instance drop potential for the instance bosses? I actually remember playing back in the day and not getting many drops from bosses at all, but it seems like they've actually given the bosses more items that seem to drop consistently (besides shards of course) I've checked MMODB and the lotro wiki but i havent seen much information.

Thanks
