Additional IP rewards
The rate of increase of content in this game, seems to massively outstrip the amount of time I will ever have to grind out IP by playing matches and I don't think it's reasonable to demand that all content is free or even that all champions are free to use and only cosmetics cost. At this current rate, not only will I never own all the content, my proportion of content own out of content I can own, will tend to zero like a negative exponential function
Something I thought was really great which Riot have done is additional IP rewards for playing in a team and I think it is a fantastic idea Riot should capitalise on.
Right now, earning IP is too much of a function of time
So why can there not be additional IP rewards for completing monthly challenges (which are still difficult or novel in some way) or daily knockout tournaments for players in each division where the prize is a share of an IP pool. Heck if finding full teams is too tough to implement, 1v1 or 2v2 tournaments on the Howling Abyss. This latter idea has so much potential, imagine how much it would feed into that LCS buzz, actually playing in a Bronze-Silver division knockout tournament, one of the reasons LCS is so popular, is because people really feel they can be like the pros, you can watch faker carry as Zed, then play Zed yourself, it's more personal and engaging than Champions League football, because nobody can ever relate to a pro-footballer, you can never find 22 people willing to play, a full sized pitch etc - a kick-about in the park is nothing like playing as Messi or Ronaldo whereas League really hammers home the "I'm just like them vibe" (same champions, same 'pitch', summoners rift, same 'kit' skins)
Playing Bronze tier LoL is more like LCS than a Saturday kick about is like the Champions League and I think psychologically this is part of the appeal of eSports
