Can’t say I’d play a Jinyu, but its not as if I intend to play an Earthen, either.
So long as someone likes the race, add it, I’d say.
The one Hozen from Jade forest is still kicking around and isn’t seemingly elderly in his dragonflight cameo, its likely that its more due to being hotblooded monkey men living in dangerous locales without a care.
Though we’ve seen other chiller hozen working with Pandarien and such so you’d think someone would notice if Bobo the farmhand is still kicking it 30 years later, though I suppose even the chill hozen still probably don’t stick to one place for anywhere near that long.
