OP seems correct with his calculations though. I've looked at it as well and if you assume that you'll always get the maximum amount of points for each character you'll find that you need to play 10 games to complete a region. (and that is the minimum amount of games you'll need to play). And considering there are 10 regions this means at least 100 games.
Math Interlude:
- Week 2 having done noxus before freljord you can get a total of 110 each game if you get max points for all characters. Both regions need 1050 points to be completed.
- Week 3 with irelia A and diana B => 253 points at maximum and 2500 points needed per region
Most likely though, people will have to play many more games than that (cuz noone's gonna get 17 kills, 15 assists, 32 vision score, 7 epic monsters, 0 deaths, ..... every single game). Hence a more reasonable estimate will be about 150 to 200 games in order to complete the entire event. Seems like a bit too much imo. It wo...
