I know you guys are joking, but I'll tackle this one anyway. The issue with the single objective--whether it be the single brush or Grez, is the unilateral chain of events that results. With only one objective to fight over, there is no longer any strategic choice in whether the objective should be taken.
As far as objective control, do you think that Red buff should be more powerful (since it's the only buff on the bottom half of the map) to make it more "appealing" and strategic? As far as now goes, it can be taken fairly easily at level 4 and even sooner with help.. and it goes largely unnoticed except for early on in the game.
