Mighty blow distance increase?
I haven’t done the math but the skill seems to have an aftercast where your character has to pause to get up and start running again. The distance covered with skill is short and I suppose with the aftercast the speed increase with using the skill shouldn’t be substantual.
as mentioned above there is an after cast when you land from the mighty blow that may cancel out any distance gained by the jump. Although I have learned of a small trick that I use often with heroic leap,(greatsword 3) but sometimes mighty blow to gain extra distance.
basically it annoyed me that when you heroic leap off an edge when you get to the end of the animation you lose all your forward momentum and drop straight down. however if you switch weapons just before the animation ends then this will not happen and you’ll get a little extra distance. I usually use it to clear large gaps in wvw.
Similarly you can do this on level ground to get around that aftercast. Obviously being out of combat is ideal so you don’t have the cooldown for switching weapons. You could give that a shot for getting to a node quickly, but I’ve always assumed it wasn’t worth the effort since mighty blows jump is so small compared to heroic leap.
