@Pindasauskanon Haha, I think I see what team that is... LeKit right? Somehow I got lucky and got through today... Maybe I had a lucky RG assist on my QGJ opening on Rey that stunned her (which then doesn't trigger his RG, and I managed to finish her before it was too late). But then I failed on the other quite similar team (saber): swap Daka for QGJ, and that team is basically all-offense-up from the second turn onwards.
Well, more generally I too have a hard time adjusting to the new Dooku fashion (which, at the moment, is 9/10 of our top-10, the last one being me -- I don't have Dooku). He certainly has won hands-down the award of the most annoying toon ever! And now, not only is he annoying, but his whole team has a chance to be annoying too!
Well, back to the original topic (RG), it takes a bit of trial and error, but basically find the max amount of damage you can deal their attacker so that he stays above 50%, then one-shoot him with an assist. Alternatively, spray offense-down or mass-damage on everyone, then finish with an assist. Or trigger the taunt early then steal it with QGJ's humbling blow. Or oppose your own RG so that it becomes a race on who's exhausting the other one first. Or stun any urgent threat while you deal with RG (there are few fast stunners I can think of).
Of course, RG with a Dooku lead adds (a lot of) spice to all of the above.
