Okay, I can do it, but I just finished fighting rank 45+'s in Lone Wolves (I WAS a 38) and I just got my -Yoink- whooped. I kept getting 4 shotted, and even though I try to the same, on my headshot I just literally have a spasm because I try to strafe and I miss my kill. Could I get some help? I want to get a 50 before Halo 4. Thanks
bump, I really want help, I’m a level 40 now and it’s really getting annoying
You should probably try to get a 50 in a different playlist if you think level 40 is already annoying. It’s much worse at level 45+.
Lone Wolves is known to be the most annoying and probably hardest playlist. It also takes very long to rank up. I only managed to get a LW 50 on a new account. I could never do it on my main account which is still a 48 Brig Gen 
At 45+ you will meet people in party chat helping each other in Oddball and KotH. That’s annoying.
Anyway, try to lead your shots and clean up kills. Maybe use a lower sensitivity to keep a steady aim. I personally use 3.
Good luck.
I recently switched to Bumper Jumper after years of using the default setting on all the Halos (except Reach–used Recon there). It quickly helped me. Being able to jump and melee without taking my fingers off the right control stick is a nice convenience.
Turn your sensitivity down a little so you don’t over correct you shots when you get shot yourself.
