In offline mode, my bladedancer from 8.5 plays great. Hold down the button, dance around killing things.
In online mode, my new bladedancer tries to use Dancing Strikes and just sits there doing nothing for a second or longer between each swing, if it even continues to swing. It’s like the skill doesn’t go off cooldown even when the timer ends, the skill stays dark on the bar. Literally unplayable, as spamming the button also still has delays between swings.
