Your situation went smoothly but it's different for every disabled vet and each claim is different. recons may have worked for you but may not work for others since each claim is different. Don't judge how everyone else needs to conduct their business just according to how it worked for you. Again, I'm happy for you and I want you to get everything you deserve. Just keep your mind open that appeals, DRO reviews, vso's do work for some when a reconsideration wouldn't be effective.
Humble yourself a little and think outside the box.
