How many responders actually looked at Acrofales' profile? How many of you understand that Zader applies slow?
Try Phasma before RG. She will need more gear and to at least fill out her mods. Speed up Vader, too. Yes, another Sith or empire toon would be best but if it's between RG and Phasma go with Phasma. Vader will apply slow so don't worry about Phasma's aoe too much. Just use her to speed up your toons. I would also suggest, in your case, not using culling blade too much. Just in spots where force crush is down to one on cool down, and the rancor or Captain's TM is next to nothing. Otherwise do not use it. Phasma is going to be the only one not to reduce TM so you're going to want to get her out of there quick. Be working on Sith toons. Empire are still kind of meh. You will probably have to use manual a lot. Don't worry, soon you'll be autoing it.
