Admittedly, I'm a little surprised to see so many Ki users this early in. At any rate, what Hatman's talkin' is a good thing to keep in mind.

I'll take this moment to clarify that in terms of strength improvement, unless there's a significant focus on raw power or speed, all Ki users will be of similar strength. Same goes for speed and durability.

For example, Jenso is extremely durable, and very resistant to all types of harm. Durability is his current focus.

Alex Also has a durability focus from the look of it, albeit to a lesser extent, but I would consider his strength lower than both Lone and Jenso's to start. I imagine after fighting for a while, his reactive Ki would eventually make him far stronger and faster than the other two, and possibly most Ki users in history. 

From the look of it, Lone's regenerative factor is just a different take on enhanced durability. Think high-HP rather than high-Armor.

Ehem, so yea.

Careful with your speed and strength relative to everyone else. If you specialize in one, the other will certainly be weaker with the regenerative capabilities you already have. I also don't really like the term 'god-like' if you're not pouring all of your focus into raw power. The way Ki affects strength is very mystical, rather than literal, as is the nature of Ki V.S. the arcane.

As long as you don't overdo it, the sheet looks fine. I'll edit Kho's philosophy a bit and put it into Saiga's history, when I have the time.
