Overwatch first impressions, Part 2: all the defense heroes, all the tanks

Blizzard Entertainment’s Overwatch, now in closed beta testing, adds an interesting mechanic to first-person team shooters: tanks.

I don’t mean tanks as in the giant metal vehicles (though Overwatch has that too, as we’ll discuss in a minute), but tanks in the role-playing game sense: giant, beefy characters that soak up damage and taunt enemies to attack them.
