Kylo is shaping up to still remain the best GL out of the 4 in the game.
Kylo can beat every other ultimate GL. Except, for Luke (squad arena only)
Luke counters SLKR but it seems that he’s only successful when he uses GAS, JKL (the best 2 non-gl characters in the game), Revan (top tier Jedi) & hyoda.
In other game modes, this would require Luke to break apart 2-3 squads to counter Kylo. Which definitely wouldn’t be worth it.
Rey can counter kylo if she breaks apart a 501st team and rebel squad. All to beat a SLKR squad that only uses FO characters.
Kylo himself, beats squad arena SEE & squad arena Rey while only taking characters from his own independent faction.
He also dominates raids and all PvE content that has been thrown his way.
Is it safe to say, Kylo is the best Galactic Legend so far? With the current testing of the new GLs (ultimate / no ultimate) it seems as if Kylo is still the best all around galactic legend in the game. As well as the most worthwhile Galactic legend to go after.
(Note: This isn’t biased because I don’t own SLKR)
