Totally have to agree with Dan.
Warrior tank has never been a big favorite for many people.
It is missing some utilities to keep up with the other tanks. The attacks speed and (low) endurance shred is pretty small compared to them.
Would be really interesting to have Deadly Gamble act like Adrenaline Rush/Rhythmic Blows that gives the party something interesting to look out for for their burns.
Even if this cannot happen, try to fix some of the above mentioned bugs for it. Would be a good begin already...
