I was just in a Whitefall Steppes, and I tried to use Reconstruct. Not sure if I moved or broke it some other way, but I started to channel it again right after, and ended up doubling up on it. It drained my charge twice as fast, but it was healing me twice as fast.

2 heals / second instead of 1 / second

anyone ever experienced this before?
