VI, in their infinite wisdom, has named both the basic and imbued enchanted dwarven armor "Dwarven Plate Armor" in EQ, while the enchanted non-imbued armor is called "Enchanted Dwarven Armor". It's another one of those long-standing errors that is still waiting to be fixed.
No...besides how would the halflings even reach that high? <grin>
I assume because of the forges and mining techniques we dwarves love to use. Brell has decided we were getting too toasty in the regular FS items. Good news is that the Imbued armour also grants +wisdom!
Hmmm Good AC + Fire res + Wisdom = trouble for a certain dragon? <grin>
