So..about those Covenant grunts...

i kinda liked the tiny grunts.

I'm a bit partial to them myself if for no other reason than they make the other figures look larger .

I am really happy that Mega upgraded to the new size. I think it's perfect. Talking scale wise they're just right for the marines and ODSTs. I have created a Master Chief using CoD figure parts (i know MB doesn't' recommend it) so he is taller than marines and grunts. It has worked out for me very well. My MC even scales well with Elites. I hope that they make an upgraded Brute with changeable armor some time too!

I kinda did the same, more of a mashup than an official Master Chief.
He looks really intimidating standing beside other figures.
