Speaking of lb, I was thinking about and if I am correct, if you grind out some leblanc games and learn how to play her before the season starts than low elo/promo games would most likely be pretty easy.
Why? Well you could place a fake lb globally and trick your opponents. Lets say enemy bot is pushing and you place fake lb in river behind them, they might see a ability and flash. You can do that WITHOUT HAVING TO ROAM OR LOSE FARM.
Now they are without a flash bot and you and maybe a lee/kha(since thats my guess for who will be popular for jg after preseason changes) will camp bot and now your bot is fed af. 20 minutes later and you probably won the game. So leblanc can basically be used as a mini twisted fate with much more damage.
Oh and the reason this works better in lower elos is because:
1. They dont manage waves as well as higher elo.
2. ppl in higher elos will ping mia more and will have more wards so they will see the lb appear on the map.
3. I am not sure how it is now but it might be easy to tell if the leblanc is real or not based on the movement(on normal patch it is pretty easy to tell just by watching their walk)
Edit: apparently this is my 700th post. Nice :feelsgd:
