Gambit as it is now, should be called invasion instead. It’s too frequent. Also, the fact that they felt they had to have catch-up mechanics in place says to me that it’s not particularly balanced to begin with. I think it should be one round but just take a little longer to summon a Primeval. Once one team reaches the more goal for summoning, the Primeval spawns for both teams, but the team that reached the mote goal first gets to invade a few seconds into the boss phase. Then a second invasion takes place for each team when their individual Primeval reaches half health. This would make invading an actual gambit, and not something that happens 4+ times during the boss battle alone.
