I understand the frustration. The coin flip mechanic can feel unfair and it certainly can give some players an edge, but it shouldn't gimp players to the point of making the game impossible. There should be good items and important resources around enough to get you through. It can just sometimes be more difficult, than on the next run perhaps.
But I do like your idea of making the enemy loot more prominent too. It actually sounds very tempting and I will most likely do something like that in the coming versions.
