While it is unarguably a bit more difficult/expensive to unlock this ship compared to previous Galactic Chases, per the aforementioned differences in energy refresh cost and daily free energy, you are still almost certain to end up with more shards than you would from a marquee event if you do the 50 crystal refreshes (plus you can farm needed G12+ pieces for Galactic Legends).
Given that a 4* ship is of marginal utility (can't use in TB, not going to make Rebels meta again in Fleet Arena, etc.) I think people need to chill out. Should CG have posted the change in drop rate prior to launch? Probably, but halving the rate in light of the doubled energy is not exactly a quantum leap in deductive reasoning.
Down the line you'll be closer to getting this ship to 7* than you would if it were a straight marquee, and that's where the real value is.
