Riot Maple tweeted the following changes for 9.4
Here's our planned list of 9.4 changes, though as usual, not all of them will necessarily ship. Crit changes seem to have landed pretty well (so far), and we're continuing to monitor folks like Akali/Aatrox for potential follow-up on 9.5 or beyond once we've seen competitive play
