I think this is a wrong approach.

The ER:survival tree gives scout and rangers additional bonusses, yet you cannot fill this tree with using pure scouting xp, survival xp, trapping xp....

You need, for crying out loud, combat related xp....

The only thing you can use for scouting xp, survival xp and trappging xp is HS:Luck...

Is this a known bug or issue? I did a search but didn't get any clear information on this part.
