Didn't see this until today, but i'm starting to think riot will revert malzahar
Delaying Malz changes to 7.11
We've got a few larger adjustments underway at the moment to Rammus, Malz and Heimer. The Rammus and Heimer ones should be good to go in 7.10, we'll be holding the Malz ones till 7.11 (probably) however to take a bit more time to work on those. One likely change is adjusting the R so its damage is split between pool and beam, which amongst other things gives better counterplay when there are multiple enemies around (ability to interrupt) and therefore hopefully allows us to put a bit more power into its ratio.
As they try to fix him, i suspect they will discover all of those points of counterplay that they had previously dismissed when deciding that he needed to be reworked. They will make adjustments which when taken to an "extreme" (as in to their old design), will have the same counterplay measures which they are hoping to introduce into the reworked version.
So there you go folks, if you didn't think pre-rework malzhar had counterplay to his ult combo, riot just spelled it out for you.
