Alright, I've seen a lot of kids crying on the forums/discord that they either got banned or didn't get diamond division. Since everyone's guides are disabled as hell (like.. people use hitboxes in ranked SMH). Here's a guide for an easy diamond division, as long as you're somewhat competent legit, and have some ranked game sense.
My ping: 250ms
Settings:
Reach: 3.1 - 3.2; veticle check, Only while sprinting, Disable in water.
Toggle on 85% Horiz, 100% vert, 100% chance
Nametags w/ Health and Distance (in my opinion, this is the most helpful aspect of cheating in ranked)
Play it smart. Never play aggro. Against gold division players, feel free to play aggro champion. Once I get to ~1.8k elo, I typically switch to safe champion. Rush mid, grab the table (and possibly a chest/diamonds, depending on the situation) then head back to your island. Mine your diamonds, and then wait for cleans. Use your reach correctly! Since you'll probably get the first hit, it's important for you to play it smart. Against other cheaters, who are more then likely being extremely blatant, use either Magician, or play like sackboy. Against Sackboy fans, camp chests, and pray.
edit: Not that it matters; but Luke & I aren't friends anymore,
