I just want to say: Thank you very much for this great guide! I just started playing again, and probably haven't played since I4. I gave up on my Ill/Rad, even tho he was my favorite character, because solo play was just too painful. Since the changes, and thanks to your guide, he is very much fun to solo.
A couple of suggestions on the character builds. I would definitely take Stamina at 22 and Hasten at 24 rather than vice versa. Perhaps this has to do with changes in I9, but I found myself out of End all the time, especially in long fights and chain fights, even with no toggles running. This was even at 20-21 slotted to this guide's spec with DOs. Once I hit 22 and took Stamina, however, all that changed.
I still manage to run low on End if I use RI the entire time and spam my attacks pretty hard, but it's much more manageable now.
I prefer SI. That's just my preference. I'd like to take them both actually, but I find SI handy when solo because I tend to go AFK (that's one of the benefits solo play, right?), sometimes for a while (to do laundry or whatever) and in the middle of mishes, and SI is nice to leave running and not worry about it.
Deceiving FFGs is great fun.
