Looking For Friends to help improve at Halo 3

Recently bought Halo MCC for XBOX one. I used to occasionally play Halo 3 with a friend who owned it, but was never that great. I play only Halo 3 slayer, mostly because I know the maps. I am decent at map placement and strategy, but I would like to work on improving my aim. Would love to connect with other users who are about my skill rank (or mildly better), to practice in custom games. Anyone looking for the same?I’m a casual gamer, 31 years old, and work in the IT industry, and I have a headset. Not looking to hang out with trolls!

I play MCC some you can deffently add me FFrustration
