In the early levels Defiance can be utilized and gives some benefit. Even so, it's a risky propostion that all too frequently leads to a hospital trip. The point at which Defiance begins to have an impact needs to come sooner and it would be nice if, in addition to a damage boost, the power also slightly boosted accuracy (too many times my Defiance-boosted damage was wasted due to missing). I also discovered that some people assumed blasters don't want to be healed now because of Defiance. I hope this is just something that showed up on the test server because people wanted to actually see what Defiance could do. On live if that trend continues I can see Defiance causing more harm than good.
At level 50 I found Defiance was not effective. I couldn't rely on it. And trying to use it was far, far too risky. The number of situations where it could be used that didn't immediately lead to defeat were very, very small.
If this ability was meant to give blasters a boost across all levels, it fails. It does help the early levels somewhat but becomes meaningless at the high-end of the game.
