I've run into a problem with the fractal and golden fractal weapons sets. By the time one gets close to earning golden, the normal fractal set is only half done. I think this is because you only earn the normal ones on lower levels, with half of the weapon drops being golden on the highest tier. But, by the time you get that far, you're almost always doing tier 4 fractals.
But, the prize for earning the whole non-golden collection is a golden weapon, which by definition you won't be able to use (because you already earned golden a long time before).
So, the solution seems to be to buy all the normal weapons with pristine relics.
But, then, once both collections are complete, there's another problem: further drops are completely useless. You can't salvage them for anything valuable.
Does anybody else see these things as a problem?
