I still don't see any benefit, heavy attack helicopters have a lot of firepower to block a position with barrage or destroy it completely, but they are also very sluggish and very slow, making them a big slow target in modern warfare.
These tasks can also be performed just as well by very light attack helicopters, drones, or lighter attack helicopters such as the T129 and medium attack helicopters such as the T629.
They are more agile, faster, have better hit & run survivability and are cheaper.
The Apache are only modernized because they are there and are of use last, but the US would never develop and produce a successor or new blocks of this size.
