Valkorion is superior to Luke in every account as far as the Force goes; one can argue though that because of them being somewhere in the same league, Luke can resist him enough for the lightsaber to count, and fighting against the lightsaber with the Force is simply ten times more taxing, especially with Luke's speed.
But still, Valk vs. Luke is at worst evenly matched, whereas Arcann, Vaylin, Senya and HoT pretty much stomp Taalon instantly.
- Arcann alone is a notch beneath Yoda as far as Force power goes. Superior to HoT as a combatant, which makes him at least Caedus-level threat in combat.
- HoT just by Act 2 is already above Vader, as Outlander he should be pretty much Plagueis-level as a fighter overall, which suits well, given Arcann is Caedus-level (I give Caedus the edge as a combatant). Hard to judge in terms of the Force other than beneath Malgus (who is above Yoda) and roughly above Thanaton (Starkiller tier).
- Vailyn is Arcann level in the Force, hard to say about combat.
- Senya is Vader level as a combatant, hard to say about Force.
- Thexan should have higher potential than Arcann, but Arcann had many years more to develop. Given Arcann's placement I would put Thexan on that early level somewhere around Plo Koon/Kira Carsen.
How the hell isn't Taalon getting stomped against 5 at once on this calliber lmao? He has one Yoda-level, one Plagueis-level and two Vader-levels on his head.
Again, not sure how Sarasu Taalon fares. If he survived longer under Abeloth's tutelage, things might have been different, but when we saw him the Pool's power was a double edged sword.
Sure, it made him even more raw-powerful than Luke Skywalker by a couple orders of magnitude, but he was starved and ailed by crippling pain.
