If you wanna try a multiplayer shooter that maybe doesn't suck, or at least sucks less:

Try SQUAD.

Bigger maps, vehicles, more game mechanics, team work and communication is generally required to win, community is generally accepting toward noobies, you can often find someone running a squad specifically geared toward showing newbs the ropes.

Not as 'hero shooter' as a hero shooter, you don't get characterized, super abililties... but your team, and specifically your squad are limited to specific numbers of various kinds of kits... you need good composition and competent role execution from specialists for you and your squad to do well.

Not quite as hardcore milsim as Arma, but considerably less 'video gamey' than a Batllefield game. Less casual and more cerebral than your garden variety hero shooter, not as tedious or occasionally intensely boring as a full on milsim.

Basically, its the Project Reality mod from BF2, but turned themselves into their own studio and game.
