Most of the optimization board is theoretical best case scenario and most likely would never work in a real encounter. At least not to the extent that they claim.
Certainly there are builds which suffer those problems. However the fact that every single damage dealing build on the board relies on producing large modifiers to damage that apply to every hit, and then hit multiple times per round should be telling.
The fact that twin strike is pretty much regarded as a must-have for any melee fighter PURELY due to it's ability to double up on damage bonuses should be telling.
Or, you know, just run the numbers for yourself. I'd suggest you go through the ranger list and compare the single hit, multi [w] powers with the multi hit powers, and see which are likely to do more damage and by how many orders of magnitude. Bear in mind that having +20 or so to damage is something that can be done with relative ease.
