You don’t blame/make fun of your “worst” player, he already knows he is struggling, no need to make it worse.
When your teammate is in a 1v1 he doesn’t need you to be his ear and brain. Just let him play.
The bomb never goes first
If your teammate dies you better get that trade kill
gl hf gg gh, keep to some etiquette
Don’t buy an autosniper
Pick up an AWP at the end of the round for your team AWPer
Don’t cheat (obvious)
If the enemy pulls out a knife in a 1v1 you also pull out a knife
If your teammate has 4 kills you let him get the 5man
When you die don’t scream or shout just call where he is
Use tab to look at the money at the start of the round to work out if your team can buy
Don’t say gg unless one team has 16 rounds
