Play as an Engineer, equip the first Carbine for now AK-5c (I think thats it) and wreck shop
Basically the engineer is the go to easy class that can do it all, besides healing/supplying ammo you'll be able to..
Have a weapon that rivals Assualt rifles (carbines are every class and can be godly)
Drop AT-Mines or Slams in high vehicle areas (they don't disappear after you die, but will disappear if you respawn and place more) You'll get pop ups 5 minutes after you died saying "Muti-Kill, Vehicle damage etc.." from mines you placed you forgot about lol
AT-Rockets or AA...your choice...
Repair kit, if that's your thing..
Most maps and games are dependant on "Which team has the most, and semi-competent, Engineers"...
Have fun flying! The damn best object to pilot is the Little Bird Scout chopper...and that's cause you can load Engineers into who repair as you fly. Hop in any other Air and prepare for AA out the ass to smack into you..best yet "Passive AA" which are AA rockets which don't alert the pilot they have been fired!
But, like I said...grab an Engy and a Carbine and grab some points and lvls. Unless you REALLY wanna do another type of class you will have almost zero disadvantage vs. any class or vehicle.
I've been playing BF since the old days, took a look at my old stats even today...1300 hours played...850 just on Karkand lol 6000 matches on that stupid map!
I loved my PKM...was ranked number 6 in the world for support and number 4 for LMG kills for about 2 years. Infantry only patch made it impossible to keep up once Infantry only Karkand dropped..I did that shit with APC's and Tanks rolling down the street!..once Infantry only hit Karkand became Nade+support bag exploit city..
The old days...Engineers only had shotguns, Anti-Tank was a class who only had PDW's, class had "Armor and Non-Armor" and could only take a few shots till they died (squishy snipers!)
Medic = God mode
LMG's had ZERO accuracy unless you were prone
AA was ONLY mounted at certain points of the map and a pilot had to manuver between them or destroy them (handling air was your own airs problem really...accept the fucking J-10)
Pre-nerf Blackhawks of death! Nade Hopping! Dolphin Dive macros!
Hell even the week I felt like a god when the PKM (Hence my name) was patched accidentally to have sniper like aim!
