A new League of Legends patch, Patch 14.9, has been released, and with it comes a number of changes to certain champions in ARAM.
NEW PATCH 14.16 CHANGES! – League of Legends
ARAM didn't receive a particularly heavy patch this time around, as many of the devs working on the game mode were likely busy with the return of League's Arena mode. But we can likely expect more thorough ARAM patches in the future where necessary.
In total, only three champions were adjusted in Patch 14.9, and all three were buffed. Smolder, Nami, and Hwei, the latter two of which had recently received buffs on Summoner's Rift, were all buffed in Patch 14.9 in ARAM.
Here's the full list of ARAM balance changes for League Patch 14.9.
