Just not all that fun

Maybe I'm missing something, but I feel like I'm missing something about this game. When you start out, you just do payload rounds. I think there's more, I'll admit I haven't played it much yet, but it really just feels like Team Fortress 2, but instead of classes you have champions that have more abilities. It seems like it's a slight change from what we've had for a long time, but it's not enough to really be ground breaking or anything.
