Speed is one of those powers/powersets that's innately hard to belence for a few reasons.
 
	 
 
	It's worth noting that force = mass times acceleration squared. 
 
	For every time that you think "if only I could hit harder" just imagine, hitting faster is exponentially more power.
 
	 
 
	And to compound this, video game speedrunners will tell you that speed always beats power no matter how much power you need. 
 
	If speed isn't innately nerfed, it's always better than everything else, no exceptions.
 
	 
 
	I personally like the power set a lot because I love the sound effect of activating it. And also hasten is cool too.
 
	However I'll also admit that the phase thing was always weird to me and I've never used it. There's no circumstance where it would ever be useful to me.
