I happened to be on vacation for the first three days of Heroic Mode. I ended up spending about 50 gems and that's only because I pushed t10 that weekend so my time was limited. If you play the game all day every day for the whole week, you can get the heroic plus without spending gems (granted you have good armor). This is not practical for most people so be prepared to spend a few gems.
