I used to play the original, and it wasn't this hard. I played for like an hour just now. and I think I killed 2 guys only. The bad thing is this while playing on the winning team. TR. the other 2 sides were working together to try to bring down The Crown. it was a constant stream of invaders. but no matter what I tried, I never could live long, except for once when I got in the turret of a tank. we survived for maybe 10 minutes. then got blown up. there were tons of planes in the sky, but I only could shoot down 1 of them. a dinky little tie fighter thing
Heck I'm always getting like 10 kills or more per each death. That's even when we're the ones being zerged and overwhelmed. If anything I think most people are derping around and have no clue what they're doing. I'm not even a part of a outfit or squad but I do pay attention to where the fights are happening on my map.
You always have to "get into" the game at first ... for me it's always the same, no matter what game I play. Be it Battlefield, Team Fortress, Planetside, or whatever ... the first few days I will be a total noob and die die die die die die die die die die die die die (kind of fun to type die lol)
Then after some time you start to get better, you learn from your mistakes, you learn to use your weapon, you stay alive longer and longer, you learn how to deal with different situations. And then you start to kill more and more people before you die.
