Am I missing something?

Wanted to try a new game and there’s always been a lot of hype around this so I got it and played like 5 matches.

When does it start to become fun? I’m still using the starter guns/equipment but I can’t imagine the game will drastically change for me especially in terms of content?

Think I got to level 5 difficulty and tried the 3 different maps then got bored and haven’t got much interest in going back on. Am I missing something or will the game always be the same?
