I do find the weak stamina odd, but I enjoy that for once an MMO is taking the racial physicality into account. For example, look at Tera, there's a race called "Elin". In the game, their size doesn't have any true negatives, but in reality, being a 4ft tall rabbit-person wouldn't be good for you. Even with speed, a Kypiq would be like a flea to a Brudvir, a simple backhand from their 6ft 2in, 220lb frame would hurt them. If this was any other MMO, their physical appearance would be purely cosmetic.
