This is a wonderful guide you have put together; the rundown of each power chosen at each level, how to slot them and why is the sort of thing that distinguishes this as insightful and helpful. The remarks on alternative slotting/powers is gravy. Well done!
A couple of questions...The Steamy Mist/Super Speed combo seems to be one of the better aspects of the build, so why not take advantage of the tactics it allows as soon as possible, maybe even in your teens? You would have to move Hasten up as well, but it seems like it would be worth it. Also, Hurricane seems to be really far down as well and some people contend that it is one of, if not the best power available in the strom summoning line so why not take it much earlier as well? Maybe push Hover/Fly and Manuevers/Tactics farther down to accommodate them? I may be looking at this a little too much from a (kinetics) defender's point-of-view, but that is why I am asking.
Again, this is one of the best guides I have read. The in-depth analysis is not just filler unlike many of the guides you run across. Great Job!
