yes. it is true. Sure, all depend on the player need at the moment but yes. Also, in the silver box accounts, you have to buy the boxes. Still cost. Few items are close to the old silver accounts, but it is a bit more expensive and have to wait. In the other side, you can craft stuff that you might risk for it.
I used to use L2 to get RARE/Common when started the base as best option with a new account and keep moving to a close similar simulation of silver box. It worked fine for my farming habit. Power kits came later due to cost but for a good grinder it is a good option post some point in the progress where you can save more and advance with less worries. Just smart play to progress.
Some months ago, a player set an order of 300 million for legend/epic. A 378,000 gold per part
