[Lordaeron] Question Regarding Random Dungeon Finder

I am considering starting a character on Lordaeron and am wondering whether there are any specific rules and limitations adapted to the feature that are unlike the ones on the Icecrown realm like reduced awards past the first dungeon or something like that. Basically my questions are as follows:
• Are RDFs spammable on Lordaeron?
• Does each boss reward and EoT per kill and two EoT's upon completing the dungeon (like on Icecrown) or do rewards or RDF function itself become disabled past the first dungeon finder for the day?
Thanks for the support!
