Same here, and I agree to your post, but this has been discussed in several other topics, I suggest you look them up.
As far as it stands, Realism (the default mode) will play like in the beta.
There is a slim chance the hardcore mode will incorporate some changes that make the game better for people like you and me, and a slightly bigger chance that custom server settings will fix alot of the issues.
I wouldn;t bet on anything though!
For me this has gone beyond a realism argument. More so because RO2 isn't realistic at all, and between the magic bandages and squad spawning, there should be room for less powerfull smg's, as they are, literally awesome in every single situation I've so far encountered in the game, at almost ANY range.
Some situations the rifles are pretty good at, but there's nothing that can't be done with an SMG.
Alot of things have (not) made it into the game that aren't very realistic, to improve balance and playability. I can understand this. But I can also understand that some people believe the rifle : smg balance, is totally off, and that it hurts gameplay.
