First of all:
Now, the post:
The Trait of venoms of the Thief (Leeching Venoms) should be changed to another tree (whichever!).
For example, in Mortal Arts is more related, like in topics and other traits, or in the Acrobatics tree there is no skill trait.
In Art of the Shadows it has little to do, it doesn't combine with the stealth traits and with the style of that tree (stealth, pause and potentiated blow). Worst it, means sacrificing Stealth skills for Poison skills, gained little or no benefit.
When are you going to make this change ?? A lot of people have been asking for it for a long time!
