I'm not trying to argue here. I'm just trying to figure it out so sorry if you felt that way. But zetas and omegas do increase your speed of ships so that's a huge "boost". You're right in regards to the amount, but in ships speed is a major factor correct? For example, Vader at g12(0 extra pcs) lv85 with all mods 5*lv15, 7* ship and all abilities at 7(no omega or zeta) has a ship speed of 171. Throw omegas and 0 zetas and it's bumped up to 173. Throw the last two zetas on and it's 174. Again, not much but a factor. That's just zetas. Every piece of gear, level, ability, stars increases your ship. See for yourself the difference it makes.
