Ability MAT challenge Omega drop rate.

I've had 12 in a row zero omegas. I would like the devs to look into it not being so incredibly stingy with omegas. 1 out of 3 tries, I'm fine with that lately cause I don't even get one 2/3rds of the time. Then I go on long stretches of 12 and 15 with no omega and zero omega in ship challenge or zetas. I notice this typically happens when there is ways to get omegas in crystal purchase packs in the store. Leads me to believe the drop rates get doctored around these times for the impatient folks to spend for what they need. Anyone else notice this? Also, bare in mind, there are thousands of players and I don't expect people to respond to this like they speak for all of that thousands. I'm referring to what I'm specifically experiencing.
