I'm low on Halo 3 color variant grunts. I would LOVE to see an all grunt pack.
The armor colors would be orange, red, green, and purple or translucent (instead of the purple).
I need more Storm Elites in the dark blue or indigo color as well as Red. Couldn't find enough of those. Would like to see the Red in a set as multiples.
Skirmishers however are the ones I need the most. They are the ones I have the least of. Not to mention, there are still several ranks of Skirmishers that Mega hasn't made yet!
