Bungie, this last season you changed the focusing costs from 1 engram to 3 or even 5 engrams. After trying to farm reputation to acquire the engrams and focus them, they are definitely no longer worth the effort. With some weapons potentially having up to 12 perks in just one column, it makes trying to grind for the godroll an impossible task. Please either revert the cost back to one engram or change it to have a guaranteed engram drop after every completion.
