Keeping it simple and short.
With changes people are asking for like:
Crouching
Marines not being able to see well due to flashlight.
etc...
Why do you want this game to be every other game out there, just with an AVP skin?
I don't understand wanting features from other games put into this game, because then this wouldn't be this game. They made this game to play a certain way, if you don't like it, don't play it.
The marines are supposed to have the flashlight be weak.
Trophy kills are supposed to be both a blessing and a curse. They aren't "cheap" kills, they're KILLS. I am really trying to understand this mindset of making the game your way. It's an experience they set up for us to execute. You either like it or you don't.
Balancing issues, bugs, graphical and server problems. These are things we should complain about and try to get fixed, but what is the f**king point in asking for major gameplay changes? This is the game!
