As it is now it is my most disliked game mode in battlegrounds. It gives so much advantage to the team that catches the two orbs first as the strat is quite simple, take the two orbs, transport them to your spawn point and then the entire group has just to defend while the group with only one orb has either to participate in attacking the other group risking to lose even that single orb making it worse to come back or to stay back at own base leaving one player less (minimum) to attack for getting another orb.
We could simply reduce it to: Make a dash for the three orbs and whichever team picks up one orb more than the other team wins.
