They're talking about how in Beta 1.x, armor spawns were dictated by static values in each map's item/weapon loadout file. For example, the standard was a 15-20 second spawn time (I think), which facilitates armor camping. This has been dramatically improved with Beta 3's dynamic spawning system, where weapon/armor spawn times are controlled by the number of players in a server instead of set values.
