You know it hasn't really changed anything though, right? Light level is still needed to participate in missions, strikes, end game, etc. I am not even sure if the character level is even needed.
A lot of the supposed changes are really superficial. Light level and XP level makes no difference. The bounty changes are not really big things, they are mostly changes of presentation.
To be honest, I am struggling to find one truly meaningful change to the fundamental game.
It is exactly the same as year one but they simply changed the presentation and tweaked some of the reward systems.
