Lagging in bot games...

We should have some sort of offline mode where people with high ping can practice. During the day there are 3 people on my internet (4 including me) simultaneously. My little brother watches YouTube on my laptop, my older brother watches Netflix and plays Xbox live, my mom goes on Netflix on a separate computer... What im trying to say is that my ping is utter shit during the day, but i would love to practice/ play bot games without lag. I hate having to wait till 10PM just to play one of the greatest games ever. Especially on weekdays where i lose a lot of sleep because of having to stay up so late just to play. Riot, can we have an offline mode? (I get a steady 43 ping when my family isn't on the internet, but 1k+ during the day).
