Onslaught = Extended Battle for Point Payload minus the Payload?

Is it just me or is this game mode just like the point battle for siege? But worse since it's repetitive, just standing on a point and getting kills without the excitement of back and forth pushing of a payload.

I'm a player who don't care about personal kills and only want the team to win so it's quite annoying that even though standing on point is the most mathematically efficient way of getting tickets, but they still choose to go around hunting for kills. Securing low health targets is one thing, but running around like a headless chicken is another.

It's just so boring for me because there is no shift in pace. In siege, there is a point battle, a pushing phase, and a defending phase. In payload, there is a pushing phase and a defending phase. Onslaught is just what feels like an endless point battle - nothing else. It feels so mind numbingly boring.

Can't there be more things added to this game mode to change things up every few minutes? I dunno... Maybe move the point around to another location every now and then? Just please add anything to change its gameplay and add phases to it for a sense of progression.
