I’ve wanted this to be changed for a while, before the announcement of a limit to Spoils of War, although I guess now it would defeat the point of doing so (and would have been worse before, I guess).
I don’t think I’d ever be as disappointed with receiving multiple copies of the new legendary vs receiving no copies of a new legendary due to multiples of old ones.
Probs not the place to discuss this, though 
my apologies.
