This task works in a strange way, but is also reserved for specific modes. In some it is easier to complete and in others it is much harder.
Several times when playing as a defender in Invasion mode, I have managed to complete this mission, but I don’t know what is triggering conditions.
Besides, I often had a situation that I took 75% of the control point, then died and the task was not passed.
I suggest removing the “Capture the point” task and replace it with “Score 900/1200/1400/ points” in one battle. Anyone can do this regardless of mode and it’s less stressful.
I think a deathmatch mode would be cool.
Each team has a certain amount of points and score earned by the players ticks down the opponents points pool.
