Fenrir was one of FFXI's best summons, all it takes is for another culture somewhere in the world to say "Fenrir is our god as well as the name of that wolf from Coerthas..." and it's lore compliant, though admittedly I would rather not see him until Shiva/Ramuh/Levi. I do absolutely disagree with the concept of locking summons into niche roles again.

Future gem summons do not have to necessarily be copy-pastes of Ifrit/Titan/Garuda's mechanics either, and given how much demand there is for more full sized summons I do not see a future where "resources are not devoted" to making at least 1 new summon per expansion. Failing mechanical uniqueness, I'll accept them as glamours though I'd rather that not be the case.

(Also for goodness sake SE stop making us fight orange on top of orange and other similar light-coloured backgrounds. The time to learn that lesson was at the start of Shb with the arenas from Mt. Gulg, remember?)
