If Ubisoft reps just kept their mouth shut or used another official excuse such as "ease of development" and/or "we were struggling to hit the release date", I think this wouldn't have blown up in the manner that it did. This could also be a case of a game that's early on in a generation's lifespan that doesn't completely take advantage of said console's abilities for whatever reason, which I've heard has happened in the early years/stages of the past two console generations.
By this point, people will know whether they want to continue playing this series every year. As much as I enjoyed Black Flag, I'm on the fence regarding Unity and Rogue. But Ubisoft needs to take a breather from this franchise. The game could end up being fun to play anyway but I understand the multitude of eyes-rolling.
