So, with FF12's new event, we get Larsa. And is it just me but that's a really neat support build? White 5*, Support 5* and even Bard 4* thrown in off typical Support PC stats - EXCEPT healer-level Mind. Equip options are kind of a bummer for hybrid builds (only swords in addition to mage weapons), but that feels like an oddly versatile build. Alas, poor Gordon.
To be fair, Gordon has some really nice SBs to his name as well. He has an Attack/Mag Lowering SB after all which is an extra layer of mitigation, his default SB is actually really good all things considered (+30% to all stats and stacks with just about everything), and pretty sure his weapon draw is better. Not to mention Gordon is way better equips, getting Spears for extra synergy potential (common weapon type in most realms), and Bows meaning he can play around the Back Row.
Basically, what I'm saying is Gordon's still fine. Larsa does hurt his niche, but Gordon still has his perks over Larsa. I'd argue Larsa's a White Mage who can use Support (and unlike characters like Rosa and Y'shtola, he can run Full Break), while Gordon is better at being a Support character who can use Shell/Protectga. It seems like a fair argument in both ends really, with Larsa having a Mind stat to actually run healing magic while Gordon has more equipment to draw from allowing for more flexibility.
Gordon also has Black 3, which if nothing else gives Blindga, a more accurate means to apply Blind than Dark Buster, which is the best Larsa can use, as well as access to Confusion status.
Also Gordon can use Shields! Yeah, don't think that actually helps him much seeing as the two big ones are Basch's Shield for Holy +20% damage, which is offset by Larsa having much better Mind anyway, and Agrias' Kaiser Shield which he can't really take advantage of anyway (...no, I am not going to hype his Thundaga.)
Either way, I don't think "poor Gordon" is appropriate; yeah, his niche is compromised, but it's not like Larsa is straight up better.
