The job is effectively limited as to what content it can participate in, pretending otherwise would only confuse new players further as explaining the situation nowadays is already bizarre enough.

Blue mage is barred from participating in the more prominent side activities in the game that aren’t 4 year old fights. No Eureka, Deep Dungeons, certainly no Bozja, only meme spells that can be used in a carnival for allied seals and Moogle Events every several months. I already managed to get the jacket from this event passively, without having to touch the T2 spam strat. I can only imagine how much less useful Beast Master would be.

Even gacha limited-time draw events have more longevity than this since at least you can take your 5 star character or weapon into actual content. There is nothing misleading about this classification.
