I agree fully, The objectives need to be reworked. Minigames is just one idea, but there does need to be other kinds of reworks.
If that makes the game tedious for you then this probably isnt your game, as fireteam as it is right now, is tedious. The point of things such as mini games is to make them more engaging, rather than constantly holding f on every item you see.
Now if they cant fix that tediousness, then I suggest they do something else. Regardless of whether or not you die, as a FT member, you keep all of the veritanium you pick up. This will encourage players who want to farm loot boxes and cosmetics to play more and more fireteam. Fireteam for the suspense of playing against a pred, and all of the atmosphere that brings, as well as farming vert. Pred for playing as a pred, and all the atmosphere that brings, but less vert to discourage everyone from playing only as him.

Keep in mind, the real fun behind fireteam is trying to survive a predator, and escape, or if you are an exceptionally good team, kill him. the objectives while they need to be engaging, and more varied, really only serve the purpose of giving fireteam something to do while pred sets up an attack.
