Since I'm a first class lady I can play all classes
Actually it's true
Since I don't have all weapons and noob stuff I can't tell what my favs are, but in bfbc2 I powned pretty well with the AN-94 so I hope it's not nerfed to death in bf3. Right now I'm just trying to learn the maps and the accessories you don't need. And not to get too annoyed at bugs etc
like accept when the Join button is working and when it's not...
At the end when FSK played matches in JOTR I just played what was most necessary, and as defence leader I could choose whatever I thought was best during the circumstances. Lots of green in vwar then
Learned more from Skratch in bfbc2 to not always rush it looking around for enemies, when you have a team that might not be the best back-up, better to just sit back and let them spawn at you or give covering fire. Something that seems to be useful in bf3 too when you want to play like that.
If you will play a match and it's tight, remember that you shouldn't always spawn when the tickets are close to run out. You lose one when you spawn, not when you die, just an advice
Hope you have some fun!
