I'm in the camp that thinks the sword looks fine. It's Final Fantasy but also, they reserved it for a Limit Break- ultimate player moves that are supposed to look extra big and flashy. If it were a regular weapon, I would be more inclined to say it's too big for the overall style of this game, but as a limit break? I'm fine with it.

However, I also raised an eyebrow at what looks to be a dragoon using omnislash. IMO dragoon should've gotten a "super" jump attack where they literally jump as high as the clouds then come crashing down in FF awesomeness. Call it "Highwind" or something to allude to Kain lol who's easily the most famous DRG in FF.

Even though it's never explicitly stated, VII's characters are modeled (in general) after the class system. Tifa is a monk, Aeris a white mage, Cait Sith is a puppet master, Yuffie a thief etc. In my mind, Cloud is a warrior, but more specifically the warrior in FFI or FFIII, where they generally use swords (Cid's the drg!). Interestingly, I think of FFXIV's warrior more closer to the Berkserker or Viking class even though in general warriors could equip axes anyway. But the Buster sword/Omnislash is probably FF's most famous SWORD attack, which makes me want it on PLD or DRK. Whichever the case, I def think it strange to see a DRG with it. Because of the conundrum of omnislash being a sword attack but warriors having axes in XIV, it feels like they just forced it onto a completely different class just because they needed something Cloud in the game and couldn't decide between warror and paladin.
