Wanted to follow up on some of the topics we talked about recently in the recent Mid-Season Followup (http://boards.na.leagueoflegends.com/en/c/developer-corner/o7nazGfh-state-of-the-season-mid-season-followup).
**Cloud Drake: **
As previously mentioned we've been holding off on Cloud Drake changes, despite dissatisfied feedback on the buff's value, because we wanted to take some more time to assess its impact, particularly in organized play. At this point it's statistically only just below the average power level of the other drakes. Perception of its impact is dramatically lower however. We're going to try an experimental, and fairly sizable, buff as a result in 6.14 to see what effect impact that has. Current plan is 25 out of combat momvement speed per stack instead of 15.
There's a reasonable risk this is a mechanic that's never going to be sufficiently appreciable relative to its power however. It's possible as a result that we might replace out of combat movement speed with a different movement effect at some point (we do think strategic movement's a good niche for a drake buff). First step though is getting a better understanding of the current mechanic, including whether it's actually good for the game if strategic movement offered in this way is really strong.
Will be our next class update in the end of year Pre-Season (November or December). Statikk talks about our goals in some detail in the link below. TLDR is more diverse assassins with more ways for other players to interact with them.
A number of support focused changes are coming in 6.13 (which probably releases next week). We've also got some champion changes that showed promise but need more testing time. We'll probably have at least some of those in 6.14 (Leona, maybe Sona, possibly some Alistar stuff we've been playing around with etc).
In terms of the 6.13 changes some of the most significant are those to the XP system and to some items. Couple of posts below from Xypherous that run through a lot of the thinking behind those changes:
**Focusing a bit more on Pro Play in 6.14 and 6.15**
Finally we'll be prioritizing work on champs that are particular problems in pro play a bit more in the next couple of patches (6.15 is the patch for most, or possibly all, of the Worlds qualifiers). First up we've got changes to Rek'Sai (initial thought - slower tick rate on Tremor sense?) and Azir (less early damage, more of a marksman like damage curve over the course of the game?). There will probably be some more changes prioritized by pro play impact in 6.15 too (Viktor and Karma look likely, potentially others like Elise?).
