How does everyone have so many legendaries?

So everyone I see on the forum has like 10 legendaries while I’ve put in my fair share of money (maybe 400-500) and I only have 4 legendaries, let alone the omegamoids to upgrade them (because I don’t have fully upgraded legendaries so I can’t get all the omegamoids from events). Just wondering if there’s some secret I’m missing out on or something…

There are special side missions released every now and then, it’s a lot easier to get the omegamids that way rather than the ladder etc events.
