I made a topic about how it reduces dash ranges but there’s actually some more interesting stuff about this trait.
I haven’t confirmed for sure but I am pretty sure it reduces all of your ability activation times including utilities. That’s very useful with physical utilities like Stomp or Throw Bolas, signets, banners, etc… There’s a trade off with dash skills because they move slightly faster but go slightly less distance.
Still not sure because it’s hard to test and I’m not going to video capture and look at the frames. Simply too lazy. But this is how I think it works.
