Slash Dash should have full invulnerability, not just health.

[Yasha-7HS]

Simply, Deimos is going to allow us to swap some Warframe powers right? Well, for those reading this going forward it is important to note that Slash Dash does not give shields invulnerability, only health. You also cannot recast this ability before its duration's invulnerability expires. 

This means that enemies, who are not losing any accuracy against you due to how the ability is coded, will constantly be shooting you while you slide across the ground and instantly waste your shields, thus using up your shield gate while you're unkillable. However, you are locked in this animation for quite sometime, even if you consider cancelling the ability after only hitting a few of your targets. You don't get back control of character instantly, yet you can die in the same few frames that you lose invulnerability. 

"Slash Dash knocks down targets" it does not target everything even in its effective range. In particular, if enemies are too close to each other when you start the cast and then drift apart, you will noticeably do one of three things: not target one of them at all, target one of them and hit both yet only get one target worth of combo count, or "hit" one of them but do no damage or CC either of them. Not to mention, many enemies will stand back up instantly before your ability even ends, and track you with perfect accuracy, or even shoot/cast abilities while trying to star in the Life-Alert commercials. It's been years and Heavy units still cast their radial knockdowns while eating S#&$, or Ancient/Scorpions hitting you with a grappling hook while ragdolled. And all of that does not mention targets that can not be knocked-over through various means, such as an Ancient Healer existing within a football field's distance of a target, or enemies that were busy in another animation so they ignore it entirely. 

"Use Augur Mods" Unfortunately, this adds at the moment its cast, which does nothing but waste your overshield as well. This also extends to things like Guardian and Shield Charger. The only way to have a reasonable chance to survive a shot in the last frame of Slash Dash is to have Arcane Aegis proc'd, which is unlikely in the first place. 

"Use Radial Blind" Slash Dash has no synergy with this ability, and in-fact ends up wasting your time, energy, and potential damage bonus while providing no benefit at all. If enemies are already CC'd by a stun, Slash Dash doesn't even have a point as bullet jumps are faster at base, cost no energy, and do not lock you in an animation. Just pressing the aim, shoot, or melee button instantly cancels bullet jump's animation as well as allowing you to do far more significant damage while reducing enemy accuracy. 

"Use Radial Blind while you have Exalted Blade" You've added 25 energy cost, lowered your DPS, and gained nothing considering EB can be used through walls providing effective invincibility. 

"Deimos will allow you to change the ability, who cares if it's bad?" Being able to finally put a useful ability in its place does not excuse the fact that the ability is more than subpar in the first place. Not to mention, making the ability more useful simply adds to the amount of options that we'll have to change out for other frames for diversity instead of everyone using like... Mach Rush or something.
