I'm on my phone right now. Didn't the v2 fix that so it has a duration and area it covers each use?only ranger knack that is "strong" is See the unseen. It's still missing what kind of time is needed to get that vision.
a useful 5th level ability that last an hour.
the rest... too week, too circumstantial and most need 3 weeks to start working.
and comparing to beserkers, fighters and even rogues, just worse.
