I have had my Ill/Emp at 50 since I2 and found this guide to be very informative. My toon is now PvP spec'd but this guide does help a ton with the PvE aspect of things. It seems like you took a lot of time and effort into making this guide and I commend you. Great job!
Also, people say "LoL 2ndary Empaths", but an Ill/Emp on a team is much more stable than any "Empath Blaster (Defender)" out there because of its team-oriented effects. Besides, slotted properly, the differences between the 2 are not that great! Although in PvP, you can actually see the differences tremendously between a defender and a troller empath.
