First of all, this is a nice addition, and thanks for writing it.
Two things to note, however.
1. In the "Your Role" section, you may want to re-count the number of enemy positioning powers.
2. Regarding Force Bubble - As of sometime around I6, the endurance cost for this power has been drastically reduced. I've found that my FF defender is able to run this in addition to Dispersion Bubble and Stealth and still attack (note that this is with 3 slotted Stamina and Force Bubble 2 slotted for End Reduction). This has made the power much more useful for soloing, especially in light of the I6 defense reductions. You still don't want to keep it on all the time due to aggro, but it has become much more commonly used for me when soloing certain opponents (DE and Paragon Protectors, specifically).
However, please note that the size of Force Bubble may be problematic for some secondaries (due to the range) assuming there aren't corners to trap the enemy against. I don't know which other secondary sets may have problems... my FF defender is an FF/Psy, and /Psy has very long ranged powers.
