So whenever the topic of new races comes up, there's always one argument that always irks me.
It's that, "so and so can't be playable because of [insert lore reason here]". Like, for instance, the Kodan and Quaggan can't be playable because they're pacifists.
Here's the thing though, a race's culture does not define a character's personality. I always roll my eyes in fantasy stories when you have dwarves that are always like "I'm a dwarf so I have a beard and love drinking alcohol and I work in the mines and am super manly all the time because that's what dwarves do." or that all Orcs are big and strong, all Elves are extremely well mannered and swift etc etc. Basically, why do fantasy races always have to be walking stereotypes of their own nation's culture?
Especially in Gw2, has done well to establish that a character's race doesn't define their personality with characters like Tybalt. Heck, going back to Quaggan and Kodan, there are Quaggan and Kodan who choose to fight seen everywhere. There's an entire Quaggan village in Hirathi Hinterlands that is almost empty because all the young Quaggan left to fight in the war against the centaurs. We have Quaggan fighting alongside us in the Pact, the Quaggan path in the personal story deals with helping them stand up and defend their village instead of running away. There's a decent amount of them who are not pacifists.
Heck, by this logic, the Asura shouldn't even be playable because a scholarly race like them wouldn't lower themselves to barbaric acts of violence. But, here we are, running around in the field as an Asura, fighting monsters and getting our hands dirty. Being an Asura warrior is the least Asura thing you can be. (Bonus points if you went Vigil) but we can do it! So if Lore was ever a reason to have a race not be playable, we wouldn't have Asura,
There are other examples to pull from also but I think I got the point across that this argument is always BS when it comes to new races being added to the game. Any race is game and lore is never a valid reason a certain race cannot be playable. Well, you know, unless they're basically extinct like the Dwarves.
