HH are complimented quite nicely by the TC aura and also stomp/wave. This build is most effective in team games 2v2, 4v4 etc due to the fact that HH provide military strength from early on and scale well though most stages through the game, especially thanks to their upgrade on t3 beserker form.
Tauren Chieftain (TC) and Headhunters (HH) is an unconventional strategy to see in solo, but it does see some use.
