Request for the developers:
When doing these Barbarian trees, please ensure that Glancing Blows from THF weapons cause special effects according to the defined percentage chance for Glancing Blows to cause special effects. For example, if I have GTHF, Mad Munitions 3, and Blood Strength, then each of my Glancing Blows should have a 15% chance of healing me 1d4 points. Not a 100% chance, not 0%, not any other number but 15%.
If the designers decide that some special abilities (such as Pain Touch) should have a higher or lower chance to trigger on glancing blows, that should be mentioned in the specific description; don't make us guess.
As a related request, it would be nice to have Glancing Blow Special Rate included on the character sheet below Offhand Proc Rate and Doublestrike.
