Riot is considering a system with a large patch every month, and smaller patch every two weeks
That applies to balance patch for patch changes, skins and new content shouldn't be affected.
The main benefit for that is that they will able to switch between the larger and smaller patches to tackle the problem that the game currently has, stuff like AP itemization and melee fighter itemization (Diver items when?) and ship them throughout a season.
Personally, I like it. Having a month where the meta is essentially refreshed, with a tuning patch after two weeks to make adjustments (and hotfixes when necessary) sounds like a nice pace. We still get the same general balance cadence, but every other one makes a bigger splash.
