So yea... basically what the title says... how do you enter a game and communicate and work as a team with people who don't even speak english? This keeps happening to me in games.

Pings. Plus, most non-English speakers still understand:

bot
top
mid
jungle
mia
gank
blue buff
red buff
dragon
baron
turret
hue

Just remember to type in Hue or Ja when you laugh at the enemy so they understand.

I'd say pings.
Ping patterns can say a lot if you do them right.

I was having the same problem a week ago. I kept playing with a chinese team and i had no idea what they were saying, except for annie when she hit godlike she announced it to both teams lol
