Seems like a useless thread. You contribute nothing and expect people to discuss? If you really wanted people to talk about this, you might throw in your own ideas or give us something to discuss. You could use your search tool to get what you are looking for otherwise.
The OP is obviously new to the forum, do you just stay logged in to this site so you can be a total asshat as soon as somebody posts something ?
I would check out youtube vids buddy, watch a few and see what you think might work for your style of play. Try to ignore the asshats that think that this forum is just for them, just like the COD online community most people on here are just waiting for a chance to be a douchebag.
Hello old mate, gallp here.....wow broad question....where to start...heres 3 tips that may help;
1. Know your play style (run n gun, flanker, camper etc)
2. Know your strengths and weaknesses within your style
3. Select load outs and game types to play to strengths and not weaknesses

4. Elite Tutorial Vids
There are, of course, many more.
