Those are both valid observations.

Perhaps some sort of formula and mechanic could be put into the game to make a zerg itself a target on the map. Perhaps if you get a large enough concentration of players within a certain amount of space on the map at one time, that zerg can be dinged on the map as some sort of "massive troop formation 1/2/3/etc", with a symbol hovering over the formation that denotes that it's a zerg. The map and the symbol can even track the zerg as it moves in-between bases, so that players can be aware of where it's heading.

This would serve a purpose of basically putting out an open season hit on any zerg on the map, and players from the other factions could flock to fight it or bunker down to stop it (or avoid it, though I think that it's in our nature as players to want to engage, rather than go around).

As well, it could also add a certain level of logistical depth to the game, with organized outfits having their troops move in a more scattered formation as opposed to a clumped up mass, so as to avoid showing up on the "zerg radar".
