Just noticed this. The heroes with most fun and interesting moves (Aramusha, Nobushi, Highlander, Shaman, Kensei,...) are either low A tier or lower tiers. But the heroes with most boring moves are S tiers (atleast Zerker is more fun to play than other S tiers). I think if Ubi can not balance the game, atleast they should choose the most fun heroes and buff them to S tier.
That tier list is for a competitive setting, where you combine a high health pool with big punishes and then wait for the timer to run out. Super fun. Zerker has high damage and HA, making offense safer and sets the pace of the fight.
There's probably more to it, but it really doesn't affect the 99.9% rest of the playerbase.
