In the waterfall level if you fall into fast water are you doomed unless you happen to wash up somewhere convenient? I found that often even when I was wedged in front of a rock, jumping didn’t seem to reliably get me up and I just kept losing health. (It only now occurs to me: should I have been trying to swim upstream to briefly create some space and then jump?)
P.S. Thanks Josh and ArenaNet!! This is hilarious. An absolute riot to play!
