He's pretty good as an Anti-Jedi character. Currently mine goes last but goes twice. With his update I don't see that going away, only getting better. Plus it gains Speed Up every time it's not attacked which is almost a Taunt yet has a Counter.
This is definitely a buff for the upcoming inclusion of General Grievous so I wouldn't suggest new/F2P players start farming this one right away. But for those of us who have him on a quickly dying droid team HK-47 and MagnaGuard are salvageable units to counter the new paradigm.
