I'm returning after a little over 2 years aways from away from the game. I never played a Jedi Shadow and want to give it a try. Previously I played a Sentinel. I will be doing mostly PVE with a friend who will be playing a Jedi Guardian. I have no idea as to the different play styles between the Serenity and Infiltration Shadows in terms of duoing and solo. Is there a big difference? Does either have a harder or less forgiving rotation to learn? Thanks for any help, ideas, or tips to good current articles.
