We don't. A distraction actually detracts from my proposed plan. Here is the reasoning:
Let's assume that both sides have an equal amount of people. This isn't the case for Carida, but if we get enough allies and One Sith to show up it could be. But, let's assume a theoretical battle had 10 people per side. There are 3 objectives that determine victory: objectives A, B, and C. Winning 2 out of 3 objectives equals victory.
There is no time limit, though. And this assumes that the objectives can be recaptured by the Defending side.
To start the battle off, the Defending side may arrange its defenses however they want among the three points. However, the Attacking side goes full 10 to Objective A.
The Defense has two choices in responding to this: commit a large but not equal force to A while leaving some people behind to defend B and C, or commit everyone to A just as the Attackers did.
Either way is a win for 1 Objective for the Attackers, assuming equal forces and strength.
Situation 1: Defenders commit everyone to A.
In this case, Defenders commit all 10 to A. The battle rages on for some time at an even level. The Defenders may suddenly think that they got a slight edge because they seem to be winning. Suddenly, they lose Objective B. What happened?
Because Objective B was undefended and the Defenders were focused on one Objective and huge fight, 1 person from the Attacking team slipped away to covertly take Objective B while Objective A had a 9 to 10 fight in favor of the Defense.
Result: Objective B for the Attackers.
Situation 2: The Defenders commit a large force to A while having a meager force at B and C.
Imagine if the Defenders had a 8-1-1 defense for A-B-C.
There are two ways the Attackers can handle this. The first is to power through the fight at A. Due to having a numerical advantage, the Attackers will start winning. It's a slow battle. Yet, if the Defenders abandon B or C for Objective A or if they commit more people that necessary to look out for B and C, then the Attackers end up having an advantage either by sending someone to sneakily capture an Objective or by powering through a smaller force of Defenders respectively.
The second method, which is more high-risk/high-reward, is to organize a sudden switch in which they left a small amount of people at Objective A to distract the 8 Defenders while they overpower the 1 Defender at B.
So if the Attackers managed to successfully win an Objective that can be recaptured, what happens? Plans change. The Attackers have to successfully ward off the Defender's counter push to retake the Objective. Let's assume it's Objective A that was captured.
If Objective A was captured because it was undefended, then the Defense will likely wise up and do the 8-1-1 Defense.
Now, the Attackers can't just do a massive switch and abandon Objective A completely.
But if the Defenders are pulling an 8-1-1 Defense, then they can take 2 Attackers at Objective A and send them to either B or C. Thus, this creates a 2 to 1 advantage. If the Defenders abandon the third objective to help defend the second, then 1 person can split off of Objective A while the 7 Attackers left try to stall the 8 Defenders long enough for the 1 to sneak in an Objective capture.
The only way for the Defense to counter this with even numbers and skill is to completely abandon the captured Objective and turtle the remaining two. Even then, the most likely conclusion is a stalemate. Though, the natural reaction is to try and retake the captured Objective. Therefore, this is a reliable tactic.
If the Objectives cannot be recaptured by the defense, then that simply favors the Attackers even more. If the Attackers have more people, then that favors them even more.
The only way where Objectives do not provide a huge advantage to Attackers is if the number and skill of the Defense is too high compared to the Attackers.
Therefore, piling everyone on one objective, at least initially, is the better solution for victory.
