Didnt we kinda have this in D1? I could of sworn when crota's end came out, all we had to do is wait it out after defeating croat (last boss) and it takes you to the scoreboard. I could be wrong but I do remember doing something like that.
While I def dont want to wait lol, but yea maybe pulling out your ghost at the end will display the scoreboard or if you beat the boss theres a screen you walk up to and interact with that let's you see the results.
But I much prefer a regular scoreboard after defeating the boss. Let it pop up for abit and we can close it up.
