The issue is, they tried to "Fix" it with prime, then again with primes removal and its integration into the base game mode. They need something more to it, Have ghost mods that give you the class powers of prime, have new maps with new mechanics that will accelerate gameplay instead of having to run back and forth (Mars teleports, titans ring of speed, Dreaming city portals and teleporting pit), something needed to be done for gambit. But now i think its too late, the only people playing it are those that just play for challenges/titles, thats it
