I'm going to leave this one alone, after making this one last comment, because I'm truly not too worried about this. It may seem otherwise, based upon my participation in the thread; but this isn't a huge worry for me. I just thing this is an interesting discussion.
Okay, last comment (maybe

):
Those guys above-- they're probably good dudes. They might be great marines (I'm trying to guess by the camo?). None of them look like they'd personally lead the galaxy against the Reapers, though, do they? Didn't BioWare make Shep look like a Hollywood action hero for a reason? Those normal looking guys wouldn't be impressive enough to be leading men, for most gamers.
I suspect if people got the realism they seem to be requesting, there would be a storm of complaints. Look what happened when we got some realism with DAI. It gave us some realistic, attractive women, and all I kept seeing for months was how "ugly" the female LI options were. Be sure you're ready for the thing you request.
