If you sort all English words by frequency, the ones that contain 'e' would be distributed more or less randomly, so it seems more doable. Banning the first 100

If you sort all English words by frequency, the ones that contain 'e' would be distributed more or less randomly, so it seems more doable. Banning the first 1000 would prevent you from using the most useful words. I don't think you could construct sentences that wouldn't sound totally weird.
