Viper would of been better if it had a different name

I agree the name doesn't sit very well for me either. Perhaps it will grow on me with time.
My problems with it based on my OCD tendencies:

1) Other job names can give some clues about the nature of the job (especially based on final fantasy lore).
2) The new job adds another job that is removed from the "class" system; we may as well get rid of the whole thing if we keep ignoring existing frameworks.
3) The Rogue class is called "双剣士" (Dual Sword User) in Japanese; it seems natural for Viper to progress from this class instead of being a stand-alone.

With a class name like Viper, my immediate image is a whip-like weapon or at least swords / spears with serpent-like blades.
(Such as the "Serpent Blade" used by Zhang Fei in the Romance of the Three Kingdoms or "Dynasty Warriors")

That, or a job that dabbles very deeply in poisons, but that doesn't sound very "Warrior of Light"-ish either.

I also agree. The job is too "Assassin-y" in ways that beg comparison to the Rogue class in ways no other job has really done. It's just too similar to Ninja. Which in turn undermines the class system, on top of just feeling like a redundant addition.

And you are right, a sword-whip would have made more sense for a "Viper" than Zidane gimmicks. While I suppose at this point poison-sword is an open niche, I am not getting a lot of that idea from the visuals (I can almost make out venom in the lens cracks in the reveal trailer, and maybe a purple poke in the combo opener, but overall the aesthetic is generic fire-and-lightning). But, as I observed, how crummy is it that Ninja lost a unique and very Ninja-y themed skill only to have a class try to stretch "Kiss of the Viper" into an entire job concept?

I'm not a fan of the name either, unless it has snake or poison themes (which should've been shown in the reveal if it has any). If anything, it sounds more like a title or rank, rather than a class/job - kinda like how the reapers in Ul'dah are the Lemures, but you don't see the job itself being called Lemure.

That said, it's already been revealed, so unless the overwhelming majority of the playerbase disaprove of the name, they ain't changing it.

Precisely this, too. Feels like "Lemures", or even better, "Twin Adders". It doesn't communicate a solid job concept, just an "I'm so cool" title for a Hunter that wishes they were a Ninja.
