Why is Dragon Slash - Boost not an evade?

[HnRkLnXqZ.1870]

I'm currently playing Bladesworn in Open World and enjoy using it so far. Dragon Slash - Boost has good mobility. A little weird to aim and easy to launch yourselves off a ledge, but I think that is just a L2P issue. But I do not get why it is not an evade-skill. I've heard the original version of the skill was even faster in terms of movement. Meanwhile stuff like Rocket Charge (Scrapper) or Burning Speed (Elementalist) have an evade, although they are slower.

And despite their massive 'power', all Dragon Slash skills do not have combo-finishers.

Those burst-skills are OK, but feel a little underwhelming.

Dragon Slash is usable every 8s (less with discipline), and Boost's animation lasts for at least 2 seconds. It's being changed in 2 weeks, but Bladesworn is also capable of constantly spamming it by taking [Daring Dragon].

I see. Will try it out. Thank you.

think it should work as an evade, but it has a the biggest attack area of all slashes since you cover more area around you. so making it an evade could cause more issues. I'd agree that it should count as a movement ability tho.
