Crusader Subskills

Out of curiosity, where did you get that allocating points into crusader subskills gives enhancements to the main skill, e.g. every 5 Binding points = 50 Celestial Spike range, every 5 Warding points = 50 Shield of Trust range, etc.? I stuffed five points into either and I'm not seeing any notice of that.

EDIT: Never mind, I found it. It's a highlight under Warding/Binding/Smiting Level #.

Yeah, I wasn't sure about those bonuses since I couldn't tell such a tiny difference in range.

It wasn't until I got 7 Crusader levels and put them all into Binding, and saw the damage increase by 5 that I could tell that anything was happening for sure.
