I feel like thieves have the steepest curve from mid ranks to hero out of any class we have. Assassins get martial trance, warriors get legacies etc. In fact thieves seem to be the only class (outside of goblins) with no hero level skills. I had thought about third attack into all thieves organic skills (which i support) but i think a new skill at level 45 or so would be a better idea. I think building on the thieves aim->precise aim->opportunity strike is probably a better fit. So my request is for a skill for thieves post 42, I have two ideas.

Thieves eye - Continuing to build upon careful aim and understanding of weaknesses in armor, a thief can very reliably continue to land blows. These blows may be weaker than most (75% or so?) but often a blow that would usually be parried will now result in some damage.

Dirty Fighting - At this point a thief has learned to take advantage of every thinkable scenario. A gash here, an elbow there... adding a little extra to their attacks to slowly debilitate a foe becomes something of a specialty of these cretins. (Essentially i would suggest instinct of the predator type effects to normal attacks for thieves here)

Thanks guys! Merry Christmas.

While I might agree to do something neat for thieves at higher levels, these aren't hitting that spot for me. Neat ideas though!
