Object rearrangement.

less than in the sixth.

If you collect resources in the sixth game using only portals, then yes, it takes less time ;). But the overall resource pool saves the most time.

By the way, I like the restructuring more and more :). It's even strange - how did I manage without it in the fifth game's campaign? It's imbalanced, yes, but the innovation is useful. Except that, tactics really suffer - in the fifth game, there were several maps that focused on the interaction of units from different factions.
