Lore-wise how do you explain your job's nerfs/inexplicable loss of skills/spells?

[Shai]

Ther are not exactly "lost" per se, you just do not use them. Kinda like how red lotus blade is still a move, but not one used by the player.

As you evolve as a warrior, you refine your skills and learn new ones. You are never static. You continue to grow and evolve - or you die on the battlefield. So for me, when skills get stronger or simply disappear, I imagine I have just refined my way of waging combat. I have developed a new technique, a new rotation, a new counter to utilize. It gets me through the day when no in-game narratives are presented. =)
