For me it is also downside, and I don't know why SE made this decision, but well... a lot of people defend Seifer as "cool" for them, and I think it is this way because, people are in hysteria now, defending the Job-gameplay in Eorza like zealots, in fear of changes.

Everywhere You can see advertisement with Squall, as the main protagonist of FFVIII, wielding Gunblade, and basically I remember reading forum posts of people needing a gunblade Job in Eorzea, because of Squall Leonhart - we even got his outfit, his weapon, and finally the Job itself (which for example have attack from Leonhart "Blasting Zone" like Limit Break in FF8) so yeah...

I loved the Kingdom Hearts and twists to fight against Squall on arena, and its normal I like him, as I like Cloud, or Terra from other Final Fantasy worlds. No wonder why iconic Heroes are in Dissidia

I don't understand why people state that it's just Eorzea thing, and it should be 1h >__> Job ... Really? If it's 1h weapon, then why in attack some animations are 2H? For example take PLD, do PLD attack with two hands anyways? Ofc no, because he wields 1h-sword and shield. I hate when people say that gunblade is 1h weapon and it should stay like that
