I don't have any of Sky Reign's/Optimus Maximus's components in CHUG form so I am pretty excited for them.

I am curious as to why Hound is part of a combiner when he is part of the Lost Light crew (MTMTE) and the CW Storyline is part of (RiD).

The combaticons look awesome! Nitpicks are Vortex's colour scheme is a bit annoying and that they made Blast Off out of Fireflight (I thought they would though )
Brawl looks awesome!
Shockwave and Wreck-Gar I haven't seen close ups of but Shockwave looks pretty beast from what I can see.
