Whether Silver level is useless in the benefits it provides or not, is not in anyway relevant and not the point I am making. The point you do not seem to be able to grasp is the arithmetic calculations that get you to the various tiers and the impact the upcoming changes will have. For the last time:

The Bonvoy programs offers several level status. I will concentrate on just silver and gold levels to make the arithmetic simple.
If you are not a Bonvoy cardholder, you need 10 nights to reach silver and 25 nights to reach gold etc.
If you are a Bonvoy cardholder, you also need 10 nights to reach silver and 25 nights to reach gold.
Being a cardholder however, gives you a credit of 15 nights and thus to get to gold, you only need to stay 10 more nights (25-15 =10).

When the changes are enacted in July: cardholders will be given silver status and in addition 5 elite nights. If a cardholder desires to get to cold they only need to stay 10 more nights
Number of nights required for gold = 25
Silver status granted/equivalent nights = 10
Additional nights granted 5

So total number of nights a cardholder would need to stay to reach gold with the program change in July will still be 10 nights (25-10-5). Exactly as it currently is.
