"A new ally has joined the game but your enemies grow stronger" Diablo figured this out a long time ago. Destiny does scale though, they just do it the wrong way... Bungo: "I see you put the time in to hit max light level and have all meta weapons we've essentially forced you into. What's that? A buddy of yours hasn't done Leviathan? Here, let me nerf your power down to 380 so you can not be the godlike end game hero you deserve to be."
