Would it add a useful option for strategic purposes to give marines the abillity to fast-track upgrades for a heavy resource penalty, say 1.5x speed for double the cost; and aliens the abillity to get a hive up faster for a hefty cost?
This would obviously be a buff to both teams as there are more venues and the old ones are intact. It would in particular cause competition for resources to be even more important and give aliens more of a chance to bounce back after losing a second hive to a sneaky shotgun rush or similar and shortly thereafter reclaiming the territory.
Oh well, this probably belongs more in the NS2 I&S forums as it would be a big change to fundamental stuff so late in the game.
