That is the solution. I mean they can increase the drop rate of skeleton keys if they want, I have no problems with that as I'll get even more keys. The solution of the skeleton key itself is the solution to the strike specific drops. You get to choose what you want no matter what strikes you are doing now. Before you have to farm a specific strike to get it, now you don't even have to do that. Farm anywhere, get a key, head back into the strike and get the strike specific loot table at will.
