This new skill line requires 20 skill points to be completed and it's quite a lot even with a character who got the majority of skill points.
More than lower from 4 to 3 the skill points required for each passive of Legerdemain, why don't you add a Skyshard in every Outlaw Refuge?
Outlaw Refuges should be 5 per alliance (I'll check this better when live characters are copied to PTS), so it would be a total of 15 Skyshards and then 5 skill points.
It doesn't cover all the skill points required but at least there are some more to be spent.
