There is no more hero weaponry, except the choice to choose an enemy weapon (?).
Now all the players can have access to the hero weaponry, so the hero design itself is just without any use.
They promise us (not so much) a great Hero system when you have access to the rare weaponry (yes this, you, not all the other in your team) and stand up visually, i was excited about that. Instead, now i reached my Hero level in the game, there is nothing so to see.
It's just a class with some cool icon near your name and the ability to run fast and longer. You have less suppression with the Hero class too; but myself as a rifleman, colouring the screen in black and white don't change anything in my ability to fire and kill a target where and when i want to do. So, reduced suppression? Useless at this state, didn't notice a real difference in my gameplay.
Hero weapons? Just play assault class. Sometimes i see myself switching from the Hero class to rifleman or marksman. I'm a bit sad, they killed the entire cool concept preferred to make it fit/closer to the cod model.
I would call the game RO2: Assault Troopers of Stalingrad.
