I'd love to see first win of day tracking for Arena Skirmish, Solo Shuffle, 2v2, 3v3, and RBG.

With the introduction of the Primal Chaos from PvP boxes I feel this would be very helpful. Also for those of us with many alts maximizing honor/conquest gains can turn into quite the chore, and getting the bonus from the first win makes it much more manageable to cap multiple characters' honor for their weekly Great Vault.
