Wolves use a highly coordinated attack, where lead dogs harry the prey and are replaced as they tire.
Also, you need more than a simple strategy to take down an animal that can hurt you by kicking you with sharp hooves, poking you with antlers, or calling on 300 of it's close friends to trample you and your little pack to death.
Watching ~6 wolves chase 6 candidate buffalo, then quickly joining forces as soon as one target makes a mistake is incredible to watch.
Same as when they taunt individuals to draw them out and attack the flank.
And while the verbal communication of orcas is impressive, the wolves use of howls when out of sight, and visual cues while in sight is no less impressive to me.
