I added some combo's into the Fair explanation since it became faster in 1.0.9
Chakram has been updated to make it a must-have move. After all, a 10 frame buff is huge. The biggest buff this patch.
Shuriken of Light now deals more damage at all ranges by about +2% on average. This makes it my current recommendation.
Super sword barrage's distance was buffed. Now I think it has better recovery than Hero's Spin, though it can't kill like Hero's Spin can.
To summarize, this patch along with the previous ones gave Mii swordfighter 2 reliable kill-setups on 60%-80%, 90%-110% and 30+ percent combo's. Maybe revise that tier list to make him top tier now?
