The draft packs were produced to support draft play. They are semi-preconstructed so that the card pool will contain enough suitable cards to make for a nice play experience. For collecting purposes you should definitely avoid them.
On a different note, I have TONS of FotR rare cards, so if you need any cards from that set I can trade them to you heavily in your favour

See my trade list for WotR cards, too.
The videos are very cool. I wish you all the luck in the world to complete your endeavour. I completed my hunters block MW collection a couple of years ago. It was extremely hard back then, but I can assure you that sooner or later you will complete your set, too. It is just a matter of time and resilience.
P.S.: I gather that you are based in the UK? Since I live in Germany, any cards from trades etc. wouldn't have to travel too long distances
