B-Tier doesn’t mean “bad.” It means “needs a specific home.” Think of these Personas as the utility knife you keep in your glovebox. Lilith is phenomenal in dark-elemental teams, but alone? She’s a bit of a one-trick pony.
Similarly, Oberon has great support magic, but his damage output leaves you wanting more. He’s like a three-star Michelin chef who only makes toast: perfect toast, but still just toast. Use them when the dungeon’s gimmick matches their niche.
The real joy of B-Tier is discovery. You might find a synergy that the online meta hasn't caught up with yet. Play around; that’s half the fun.

Practical Tip: The “Two-Slot” Rule
Never invest heavy resources into a B-Tier unit until you have two A-Tiers or one S-Tier to carry the team. Use them as fusion fodder or for side quests. They’re discoverers, not settlers.
