The price still goes down every year, it's just at a higher price. (Not sure about your "high initial price" — was that a perpetual license?)
Note that you can renew for 3 years at a time at the current pricing. And if you've been paying for it for a while, you can always use the perpetual fall-back license: https://sales.jetbrains.com/hc/en-gb/sections/201619995-Our-...
If you're not using it, why pay for it?
