I'm silver 2 and I have pretty mid aim yet my deathmatch games are just full of people in diamond and ascendants, I've even seen immortals I like to use deathmatch to warm up and I'm trying to learn gunfight hygiene but it seems impossible...

Seriously, clearly you're not thinking because if you deserved to be in diamond/plat, you would be. Don't bring your iron/bronze ass into my matches with your 0/17/2 just 'because i wanted to play in plat'. Surely your bro won't appreciate...
