TANK WINS OVER WITCH!! BELIEVE IT!!!
Experiment tried: Tanking against a Witch in the Subway level of Left4Dead
Hypothesis: Tanking would finish off the Witch before she starts taking off massive chunks of life
Action: After attemping Hulk combinations (ripping the floor and throwing it to her) and Hulk smash (Tank melee attacks), Witch was relentless enough to keep the battle going, but to win this I had to be not only aggressive but make sure she was kept in a corner while the other guys kept hitting her (the other guys referring to the humans)
Teamwork was the key in doing this because of two things: having the Tank act as a "wall" in front of the humans, and having the guys flame/shoot her to death while taking some of the damage if needed.
Result: Michael Strahan (tank) beats up Britney Spearz (Witch). BELIEVE IT!
And this track proves its awesomeness!
