SAM Job's story will certainly be in question as it may focus more on being a Samurai not fully loyal to anyone due to the WoL being a Adventurer.

Then they have to cover 3 Story Arcs of SAM Job's storyline as 30 - 50 is Arc 1 (aka The Apprentice Arc), 50-60 is Arc 2 (aka Master Arc), and if things follow the same lvl 60 - 70 is Arc 3 (aka Grand Master Arc).
