In my last game, I placed more wards than my team's support
Upgrade your trinkets people.
is great, you should try to get it as quickly after 9 if you can. I had put down 30 as Ahri top (called mid, but our top wanted a switch), our support blitz dropped 29. The other team put down 51 total. The only person on the other team who had an upgraded trinket was riven, who went red (and put down only 6 wards).
LOL is slightly easier if you can look at your map and see where the enemy team is and isn't.
