1. I think its fine as CC, dmg to kill would be nice but I dont think thats the idea behind the ability. If there was something like enemies hit with your 3 while in the bubble gets a full dmg slash proc instead of a % slash proc that might be good ie instead of I think its 35% of the total damage as a slash proc let it be a 1:1 slash proc instead meaning if your 3 deals 1000 slash damage an enemy in the bubble will get a slash proc dealing 1000/s damage as a proc. This makes sense considering the limited range of her 3 anyway.
2. I think the double jump should be done away with and instead let her have a charge jump from the k drive which still reaches the same height as a double jump without the hassle of accidently jumping into the ceiling of the map but still being able to reach higher heights if needed. There also needs to be much much more application from the ability in terms of what it does, at this point its a worse warding halo. As far as I can tell running into enemies on it does nothing, jumping on enemies does nothing, the slam attack from it is useless since the slams knockdown range is terrible and from the quest I learned the kill range is practically .0000001m from yourself. I would like to see some kind of interaction with her 1 with this as well such as enemies you run into with the board while 3 is also active receive double is not triple procs in one hit. Jumping on enemies with the board causes either a knockdown or a stun similar to sleep. And just plain running into them causes a knockdown or a stagger on larger enemies.
3. This is just a radial slash proccer nothing more nothing less but if this above happens with it itll be able to be much much more.
4. Feels fairly weak unless if you have LoS and a huge horde of enemies then it can under the correct circumstances deal decent damage. I think enemies caught in her 1 and then caught in her 4 should be stripped of defenses this will help with the damage that she can deal later on. Other than that it isnt so bad that it needs massive damage or range tweaks as far as I can tell
