In my opinion I think there should be a League of Legends OFFLINE MODE where players will be able to play their existing champions From Last Login or, all champions. Of Course NO IP or Milestone points will be awarded. Also Only Bot Mode will be available and Offline Custom game.
I brought up this idea because their are some of us, who prefer to play on planes, at parks or simply Away from the internet( some persons like to take a break away from internet), you could be even in the woods of course no internet but league of legends Offline mode is their so you would not go rusty.
What do you think?
Please reply, I will like to hear your Ideas, suggestions etc.
