It's a tough list, but beatable. This version has better offense than a standard Dengaroo list in the frontal arc, though without the out-of-arc extra damage potential from R5-P8. The OCR4 is a pretty good substitute though since it helps both the APT shot and defense.
I faced it in two consecutive round last night with my Ghost and 3x Tala list. Won the first game 100-0 by blocking Manaroo multiple times after Dengar was stressed, but before he got his torps off, so he had no way to focus and got chewed up.
Second game was against PGS, and lost 100-60. I elected to eat both APTs with the Ghost in one round to take them off the table (Reinforced Deflectors + Crewbacca are pretty handy for reducing Alpha Strike pain), and eventually killed Dengar, but not quickly enough due to OCR4 -- The Ghost and Dengar went down in the same round which left two damaged Zs against Manaroo, and Manaroo mopped up pretty quickly. Some different maneuvering with the Z's -- which would have pumped a Homing Missile into Manaroo that went unfired -- or avoiding a maneuver that put the Ghost on a rock in good firing position one turn might have turned the tables, but unfortunately I couldn't get into position for the Manaroo block on multiple turns.
I built my list to tackle the Boba+Party Bus list that has been tearing up the last couple of X-wing nights, but didn't get to face it since it went down to PGS in the second round.
