My current Tier List for Season 8 Duel. This is my OPINION on the Duel meta.
No god outright auto wins right now in my opinion.
The best duel gods. Can beat anything and win almost all matchups below them.
Gods that excel in Duel but are not quite as good as S+.
Good characters that do well in the game mode but have key limitations.
Situational gods that can be quite strong but have several losing matchups.
Incredibly average characters that are capable in certain scenarios but have little to offer.
Bad in most situations but can work for experienced players.
Have a few winning matchups but are terrible overall.
EXTREMELY hard to win with.
Does literally nothing.
