How will C3V units affect the Metagame?

So assuming you attend a pre-drafted army tourney or other event that allows C3V units, how will affect the metagame? For the sake of this discussion, I will define the metagame as "What armies people bring based on trying to counter what they think the best players will bring."

Someone chimed in on whether or not to allow C3V units at NHSD, and this was my response:

My thinking is, if you don't want to play the C3V units you don't have to, so there is not much harm in allowing them - but I guess everyone theoretically has to think about how to counter the C3V units as they affect the metagame, so it could make a difference. I just don't see most of the units released so far as game breakers, except maybe the Marro Gnids who can take down heroes easily so people might be slightly less inclined to bring hero heavy armies if C3V was allowed. The other C3V units just seem to bolster lower rated units up.

We will have to wait to see the other units that are released, but how do you think the C3V units would affect the armies people bring?
