List of updates (SSB4)/1.1.5 changelog
This is the list of known changes in version 1.1.5 of Super Smash Bros. 4. This update became available on March 15th, 2016.
Although some of these nerfs were fairly significant, they were overall cancelled out by the heavier nerfs given to other top tier fighters, resulting in Bayonetta's position on the tier list actually improving in this version. The changes to her smash attacks were to minor to have a serious effect on her, and are still very powerful moves. The change to down aerial meant that Bayonetta is no longer able to rely on the move offstage, and this moderately affected her edgeguarding game, although it is still very strong. The most significant nerf is most likely the nerf to Witch Time, as it is now no longer as 'spammable' as it used to be, and Bayonetta mains are now forced to use the move much more sparingly. Overall, while Bayonetta is technically weaker in 1.1.5 than she was when she was initially released, this is negated by the heavy nerfs given to the other top tiers.
Bowser was not really affected by these changes. The increased air speed marginally improves his air combo potential and recovery, but this is negligible. The change to his weight did not affect his survivability much at all, due to it already being very good. The change to item toss strength is irrelevant in competitive play save for very specific circumstances (e.g if he grabs one of Pac-Man's bonus fruits). Overall Bowser is about as good in this version as he was in 1.1.4.
These buffs had a moderately large effect on Charizard's viability as a fighter. Before this patch, it was considered potentially one of the worst fighters in the game, along with Zelda and Jigglypuff, but while it is still considered a low tier, many consider Charizard to now be one of the stronger low tiers. The increase to its air speed marginally improve its combo game in the air, and also noticeably improved its recovery, as fighters with multiple jumps are much more affected by higher air speeds in terms of recovery. The reduced landing lag on its aerials gives Charizard more neutral and landing options, especially since landing forward and back aerials are now relatively safe on shield. Forward and back aerials damage buffs allow them to kill offstage more easily, especially since back aerial's sweetspot size was increased. The changes to Flare Blitz don't make much of a difference, as the move has limited usage in competitive play, but it is somewhat viable now. Overall, while charizard is certainly stronger in this version, it still retains many of its glaring weaknesses, and as such is still a weaker fighter in high level play.
