OK, Bethesda, or gamesas, whatever you're called, I know and acknowledge that you are a business and you need to make money, but this is not the way to do it. Instead of complaining, I'm going to demonstrate to you the disadvantages you will face from this new action you have taken, and why its bad and will actually lose you more money than it will make.
There is no incentive to buy lunchboxes, and IMO, there never has been. It defeats the purpose of the game, building your way up through 'grinding' is the purpose of the game. If you're going to gift yourself everything you work for, then you physically can not play the game with a purpose, as you are not capable of striving for anything.
Also, with the reduced odds of good pulls in boxes, it is discouraging to the small number of people who might spend a few bucks on boxes. If you were to tell them, "Hey, spend your money on my game to get something good, but we'll reduce the odds of you getting something great." do you really think you would appeal to your customer base?
Please, Bethesda, don't turn into EA.
Here are some alternatives that actually promote spending:
-Offer a special type of box that guarantee's a NEW rare weapon that is significantly better than the others. Also, for example, you could add 10, and after you collect all 10 of these in-app-purchase-exclusive items, you earn 3 normal lunchboxes.
-You could lower the odds of normal boxes from challenges, but keep/increase odds for purchased ones. The bettered odds would increase as the customer bought them. For example, 1 box = normal box, as it was before, the next bundle has slightly better odds, the next bundle has better odds than the previous and so on.
-Add something like smoke detectors or turrets, where they come only through the new lunchbox, but are not 'rare'. Smoke detectors could help as an additional dweller would during the event of a fire. Turrets could be mounted just outside the vault, or inside rooms, and would provide as additional assistance in any attack. Fire detectors could be infinitely lasting, but consume a little bit of energy, while sentry guns would lose health, but could be repairde with scrap common items being compiled into 'scrap' which could also be an idea for a new production room, which would actually make the game more interesting too.
-Offer some spinny wheel thing where you get a token for every 5 bucks you spend on the game, allowing the customer to eventually roll however many tokens they have. The rewards on this wheel are always very very good, unique and additional content from what we already have.
In summary, if you want to make money, do it the right way, actually APPEAL to your customer base, make a reason to spend money in the game, don't bulls**t your way out of it.
