I definitely don't max out every ship. I've been playing for about a year and only have five ships completely maxed. I have about 6 other ships that have at least one ability maxed. Almost all my upgraded ships are dark side as they have been best in arena and got to the zeta fleet challenge. I just unlocked HMF but only had enough to max out one ability. I now need rebel ships to run with HMF but it'll be a long time before I can max them with the rate of Omegas. I just wish there was a way to farm them in shipments consistently. Like with squad Omegas and zeta mats.
Ships release arent all that slow lately. 3 BH ships, 2 sith ships, Anakins ship, and now HMF. All those becoming farmable in the last few months.
Anyway it is what it is I guess. We all have the same grind. Maybe if they keep pushing out ships they will provide another source for Omegas.
