Thanks for doing the math, Marec.
Just so you know, I do care about younger accounts, and when I was hearing from a lot of folks about the zeta economy, I made a post here about it even though I had no reason to be concerned for myself. This is that post if you'd like to read it (though please don't comment -- it's considered bad to resurrect a dead thread, if you want to talk about the zeta economy more you can do it here or make a new post specifically about zetas):

And just so you know that they do listen, I noticed a brief Zeta-bonus-drops event just a couple months later, and I've also been paying attention to marquee toons and they seem to be requiring fewer zetas (which is just as good as giving us a larger zeta income). Note that in the thread I created to discuss the issue, I suggested requiring fewer zetas on marginal toons that are introduced more as stepping stones to legendaries and other special event toons while I (and many others) also suggested a small uptick in zeta income.
CG appears to have done both.
They haven't made an announcements, there's no fanfare, they aren't begging for thanks for these changes -- presumably because if they say that they've shifted anything then people might take that as a promise and then get mad when they release a toon that requires 3 zetas again. Still, they made modest moves in both directions -- special events to increase zeta income as well as reducing zeta requirements when a toon isn't important enough to justify them.
So CG does listen, even if sometimes they don't change anything and even if when they do not all of us are paying attention to the changes they make (though some of your players do notice, @CG_Tusken_Meathead ).
So keep caring about the game and keep bringing the math like you did when you want to convince CG that something is an issue. You may or may not convince them on ship Omegas, but the kind of detail you showed here will be what convinces them when other issues crop up.
