i think Tiberius said elrond has some kind of Foresight its like a passive it gives more exp because of his Foresight or something like that
Elrond, according to this thread's proposal, will be able to give a small amount of experience to a single hero via his advices and Wisdom, and, with the passive bonus of his Noldorin Armour, fasten the gathering of experience of the surrounding units; his Foresight is not involved at all, at least for what concerns the gameplay (map-revealing abilities).
I think it is not necessary giving Elrond a further Foresight-related power, since this aspect is already well implemented in Rivendell (Gildor's Vision, Círdan's Omniscience and the Palantír of Elostirion)
