Prime was awful and limited the way you could play the game by forcing you into a well, waiting to bank just to siphon, and immunity fazes. Honestly o.g. gambit was better imo, the best 2 out of the 3 made it feel more competitive cause you could come back after a lost round and taunting in between was fun, you didn't have siphon mechanic so it was really a race to bank motes and pull prime first, and primeval didn't have immunity fazes so you could one faze him with a co-ordinate team, and even melt as a solo if you popped your super at the right time. It felt like an actual race. Prime and current gambit doesnt.
