A Space Marine Scout with sniper tech can be an equivalent should they feel unbalanced. Otherwise, I don't see the problem.

I'm not even sure the devs know yet how the elite classes will play and how it will all work. The elite classes that were teased were done so years ago. A Ranger elite sniper does sound OP as hell, but so does a Chaos Possessed Marine ripping apart everyone in a frenzy. Not sure which one I would rather have sighting me.

And even from the overall mirror match state of the game we have at this point in the alpha, it has been shown gradually that asymmetrical balancing will become more of factor, which is very cool.

I am pretty happy they made the Ranger a Hero Unit, meaning we won't be seeing a ton of snipers...then again this is the only real 'sniper' class.
