I wonder if we'll ever see the old High Elf vs Dark Elf rivalry in AoS. We already know Tyrion is testing Malerion's borders, and there's certainly no love between either of the Twins and Morathi so I do wonder if we'll ever see the Lumineth and DoK or Ulgurothi beat the shit out of each other someday.

I've always loved the High Elf vs Dark Elf thing in WFB and would like to play that sort of matchup again in AoS.
How balanced/unbalanced are these two Spearheads against one another? Do the Lumineth just steamroll the DoK or are the DoK super OP and kick the ass of Teclis' favourites?
