To me, that looks like a good halfblood grinder, though I'd probably see if I could farm AI3 or t50 and get a second Eagle's Eye. Drop a Feral Bond for it.
Until then, drop the Feral Bond for another Elite Queen.
Also, experiment with Rage Potions instead of Fire Lances. Unless you primarily use them as finishers, I think you'll find that Rage Elixir is better creature control, and you can slap one on your Elite Queens to turn them into 9/1 monster attackers.
