The report touched on several important points as reasons for the change:
- The new route is far less exposed to avalanches, yet more difficult
- 2014 has seen the deadliest single loss of life in mountain's history, when 16 sherpas were caught in an avalanche in this very spot
- The alternative of using a helicopter to carry supplies to Camp 1 is not possible due to environmental concerns
Personally, I hope this decision will stick, as this was one of the riskier parts of the climb.
