What the hell are you talking about, lacking in development...... riiight. Ensare is good for revealing. But even if the Overlord sees the unit, what if it gets blinded, or the units are something like Dark Templar, and you want to slow thier advance? There is more to Starcraft than just massing units and attack moving into locations like moronic noobs do in 3on3 in Wc3. You do realize that money maps are a fallacy within itself? They were designed by scrubs who wanted fast games and have zero care for mass BCs, Carriers or Guardians for cheap wins. And if they had done that in a melee map, thier resources would be exhausted to nothing and you would probably dead before then. Slow movespeed in ANY RTS is bad. You can get picked off easily and you can't escape once you get attacked, unless you cloak, or pick up the unit in another unit like a shuttle. And even if the Queen is going to get sacked by Scouts. They would need the movespeed upgrade to catch up to it. And if the player is retarded, they may fly thier air into anti air and regret it. Plus, no retard would use it on hydras or weak units. Spawn Broodlings was designed to pick off crucial targets like Siege Tanks, nuking Ghosts, Templar, **** like those.
