03 OCT 2017 update: Data has been gathered for Anna's bonus season, which includes new heroes Elincina, Nephenee, Oscar, and special heroes P!Olivia, P!Azura, Inigo, and Shigure. All chartes on the site are scheduled to be updated after additional data from Alphonse and Sharena's Bonus seasons can be gathered.
Preliminary updates on observations:
-B!Lyn and Reinhardt continue to dominate arena defense teams as the most potent threats.
-B!Ike, while still fairly frequent, does not define the meta.
-Flier teams have spiked up again, many have added Elincina to their team.
-Kagero has been showing up more frequently again.
