This game is so unique, so wonderful, and SOOO unforgiving. It's hard as hell to learn, and satisfying as all get out to "git gud" at. Massive battles, game-play available for all play-styles, and a development team who cares.
No other MMOFPS brings a combined arms playstyle this amazing & intense. Just know that it's not easy to get into and most people have years of experience. It's not p2w even though it might seem like that. Guns are sidegrades (short vs long range, Shotgun vs SMG, etc.) and accuracy/positioning is key in all facets of play.
Give it a shot & stick with it! It's worth it!
