One thing that surprised me was that the Republic version of "Another Lead" seemed more difficult than the Empire one. My level 21 Sentinel struggled to not get knocked of his speeder, my level 18 Mercenary? Got knocked off a grand total of one time.
Yeah, the Imps get to ride through a much less populated area.
Their fight for the Dubious Motives mission was also much easier. Trying to solo Derester was like pulling teeth.
