Honestly i'm fine with it.
I'm changing character often, and my teammates change every time, so it doesn't get repetitive for me.
I'm 130 hours in and not tired nor bored.
Simply going Recluse or Executor or Duchess and trying more complex stuff still makes it feel very exciting to me. Even breaking marks with Ironeye, ulting and zipping around with Wylder, breaking stance with Raider, everything is still tons of fun every time.
