Enemies from a distance appear transparant, yes. Why, exactly, would that be a bad thing?
WAI.
I don't think it's a bad thing, just a weird one. I simply couldn't reason why should I be able to see the enemies in the form of "ghosts" if they are out of my line of sight.
Also, I noticed it happens not only to the enemies but to any npc. And it seens this behavior isn't yet very consistent, as sometimes I'm perfectly able to see npcs behind walls or inside buildings, but cannot see them when behind boxes or other minor obstacles, as in the screenshots below.
I assume this is still work in progress toght. Sorry for being so picky.
ps. Loadrunner, thanks for explaining how to insert images inline
