In my opinion, I don't think that anything available in a steel chest should also be available in a premium chest that is more than 8 times more expensive than the steel chest. I think that the shiny named items should only be available from a steel box and that truly premium items that cannot be dropped or found in a steel box should be worth that much money / bonds. I know that it is a gamble opening a box, but I would be very upset if I found a Lincoln's hat in my premium chest and as a result, I do not currently see the premium chests as value for money.
I think that last phrase "value for money" is the issue that a lot of people are now having with the newly adjusted premium boxes. If there was only the chance of rare, non-set or non-collector set items like: Howdah, Golden Tomahawk, Inno belt, sniper rifle, elephant gun, Rudolf etc from a premium box, more people would perceive them as getting premium items and being value for money.
On a side note, why don't Inno release the: Inno shoes, Inno clothes etc with good stats and a set bonus for completing all the Inno parts? These items would only be available from premium chests and would be tradable? That might make premium chests worth it if there wasn't the risk of getting junk items and you could complete the "Inno Set."
