However, once the game gets the base of everything done, and they can expand on how much you can fine tune in the game, then the number of games should be increased.
Right now, there are far too few of different possibilities of strategies to allow too many more games a day. But once more objectives are available, like dragon, baron and vision are implemented, it may make it less likely of one strategy overruling them all. I'm hoping enough stuff gets added later where you could actually begin planning for league opponents (other than banning out which type of champ they pick).
