Rise of the trios

For about a year, there has been a slow rise in increasingly powerful trios. First was obviously the Triumvirate, then CLS, Han, and Chewie. Next was Revan, GMY, and Jolee, though that has somewhat less direct synergy than the others have. Now we have DR, HK, and Fallen Bastila. There are probably a few other trios, but these four are by far the most powerful.

So, what other trios could come into the game or be reworked into a powerful trio?

Personally, I preferred the duos such as Chaze, Wiggs, and Mission and Zaalbar, so I hope more good duos continue to be released.
