Yeah, people are WAY too twitchy about the actual power digit. I just took my kid to school, came back, and dropped 100k power without having touched a thing. And my sail credit was taken off the assistant. Awesome!
The sail thing is new. But the power number? Meh. Just make sure all your runes and eq are where you left them. The formula for power and the manner in which it is displayed is obviously a fluid thing.
