It's called player balancing. Just Google player balancing. There is no way to know if it's in Destiny but I'll put it this way- the only reason I know about it is because I've had the same feeling from playing Destiny for over a year and noticed the changes in crucible the last 6 months. I started researching the internet for an explanation. It's real- it's in a lot of fps games. The jerk that said were all idiots has no idea what he's talking about.
