List of Omega Abilities?

Hey everyone - new to the forum and threads.... Is there a list of Omega abilities available somewhere for each toon? With the Omegas being so rare until Lvl 80, I don't want to spend the time farming, etc. only to find out that the Omega ability is a complete waste. I have spent my Omegas on QGJ basic and Fives (like everyone else), but was wondering where to go next?

Thanks!
