Leveling
Riot made a complete bullshit post about the amount of BE you will get and you will get more. No thats horseshit.
You only get it on level ups. For the first 10-20 levels you might come out ahead, But lets look forward to that level 150 cap
Now we dont know how many games it will take at level 150, but it sure as hell isnt going to be the 10 games that it takes at the lower levels, so unless they start boosting the fuck out of the BE gain at the higher levels were fucked.
Getting an average 75IP per game (50% winrate) and playing 5 games a day where one of those gives roughly 250 IP per day.
550 IP a day.
Now you get the BE on level ups. So at 150 it better still only take like 10 games to level up or its basically pointless to even worry about ever using BE to unlock champs.
Time to spend a shitload of money to unlock champions that you dont have. Thanks Riot.
