Well, the DvN expansion looks to be hella fun, now that nearly all the cards have been spoiled. However, I was holding out hope that there would be something for the Warlord in it. My best guess now is that we'll have to wait for the next expansion in 4 - 6 months, which will be something along the lines of CoK, to introduce an alternate Warlord and cards that are actually useful to play. Even if that happens though, it seems the current Warlord is destined to be permanently retired.
--Or is he? I actually thought of a use for him recently!
I've decided to create a 'training' spellbook. It's a book filled with the useless and/or overcosted Warlord-themed cards (Barracks, Garrison Post, Standard Bearer, the Goblins), along with a few reasonably good cards that would be too expensive to include in most non-war-trained books (Fortified Position, Grimson, Corazin, Thorg, the Dwarves). Toss in a few themes that are war school and don't work very well together (Deflection Bracers, Reflex Boots, Defense Ring). Remove cards that are generally useful so they can be placed in books that are actually good (Tanglevine, Teleport, Force Push, Battle Fury), and save the good earth cards for the wizard to poach (Hurl Boulder, Iron Golem). Then I will use this book when I know I'm up against a new player that is interested in the game, has created his first book or two, but is still new enough to get trounced by any of my regular books.
tl/dr: Use the pathetic Warlord against total newbies, to play with a deliberate handicap. Finally, a use for him! ; )
