The dragon slash change to lower the damage and decrease the charge time is disappointing. Can you look into separating 3 different charge rates into the trait line selection. The old high charge time and high damage as one option, the new medium charge rate as an option, and then the fast rate is already a trait I believe.
Perhaps look into blind immunity and weakness immunity as baseline into dragonslash. Perhaps that's too much for the fast charge option though.
I really enjoyed the commitment of charging for a long period of time for a hit that goes over 6 digits in my solo open world play.
