Chain the following: KOTFE/KOTET

Chain the following. Feel free to chain as many or as little as you want, or add more characters:

• SOR Hero of Tython
  
• KOTFE Arcann
  
• Spirit Valkorion
  
• KOTFE.VIII Chained Vaylin
  
• KOTFE.XVI Outlander
  
• KOTET.VI Arcann 
  
• KOTET.VI Chained Vaylin
  
• KOTET.VIII Unchained Vaylin
  
• KOTET.IX Outlander
  

= perfect equals
~ rough equals
>= almost equal
> close fight
>> one-sided fight
>>> ragdoll territory

Whatever Skillz says is right.

Spoiler:

Things we know:
-KotET.VIII Unchained Vaylin>>KotET.VI Chained Vaylin>KotFE.VIII Chained Vaylin
-KotET.VI Arcann~KotET.VI Chained Vaylin
-KotFE Arcann>SoR Hero of Tython
-KotFE.XVI Outlander>KotFE Arcann

So here's my chain:
KotET.VIII Unchained Vaylin>=KotET.IX Outlander>>KotET.VI Arcann~KotET.VI Chained Vaylin>KotFE.XVI Outlander>KotFE Arcann~KotFE.VIII Chained Vaylin>SoR Hero of Tython

I have no idea where to put Spirit Valkorion, but he probably tops this list overall.

Spirit Valkorion >/~/< SOR Hero <<< KOTFE Chained Vaylin ~/< KOTFE Arcann >/~/< KOTFE XVI Outlander < KOTET Chained Vaylin ~ KOTET Arcann <<< Unchained Vaylin ~ KOTET IX Outlander <<<<< Peak Valkorion

SOR Hero<KOTFE Chained Vaylin<KOTFE Arcann~KOTFE XVI Outlander<Spirit Valkorion<KOTET Chained Vaylin~KOTET Arcann<Unchained Vaylin~KOTET IX Outlander<Peak Valkorion.

Edit: Didn't see the ranking of the different arrows lol. Don't assume all of these fights are close (though some are) I just didn't read the OP properly.

Spirit Valkorion is before or after consuming Vaylin spirit ?

Peak Valkorion>(?)SWtOR Vitiate>SoR Revan>/=KotET.IX Outlander>Unchained Vailyn

Peak Valkorion >> KOTET.IX Outlander > KOTET.VIII Unchained Vaylin >> Spirit Valkorion > KOTET.VI Chained Vaylin > KOTET.VI Arcann >= KOTFE.VIII Chained Vaylin > KOTFE.XVI Outlander ~ KOTFE Arcann >> SOR Hero of Tython

It's not perfect but that's about where I have it. I'm not really sure how big the gap is between KOTET.IX Outlander and Peak Valkorion is so I just put >> for now. I may revise this in the future.
