This is the first season I've played this mode and while it can be fun sometimes, it's really not that great.
So, it's king of the hill, basically, with premade loadouts. But anyone who knows anything realizes a lot of the loadouts are not equal, especially when coupled with certain character abilities.
A lot of times, you're better off not even trying to board the train, let alone capture it. You're better off letting it be captured than dying yourself given how long it takes to respawn. That's bad design. And I'm not sure it would be that better if everyone started on the train. It's too small.
I was joking that certain people wanted Apex Legends to occur in a really small room where everybody could punch each other instead of using any strategy at all. This is pretty close to that.
