Yea the racial animations aren't balanced quite perfectly.. They kinda over-compensated the small races attack ranges trying to match the big ones, and ended up making them have the best ranges overall, tho it varies from class to class.
Check out this vid, it shows it pretty well:

From what i can tell from the vid:
Lancer:
Yea female amani has really poor range. Male is slightly better but still bad.
Popori is pretty average. High elves and Elin have a substantially longer range.
Slayer:
All over the place, I think this was maybe the first class they made and they just went nuts with the anims not worrying about uniformity, almost every race has some variations.
-Male castanic stands out a lot with the huge leap on the 4th swing .. And yea while move range doesnt necessarily mean attack range, its still important in many cases.
-Amani mostly average here unlike other classes where they often fall behind.
-The 4th swing is very different between small and big races.. Small races mostly get a 360, double hit, where the first hit does less dmg.. Maybe 30%/70%? vs the big races which just get a bigger linear one shot damage swing. Don't think it's balanced, as more hits gives you more crit chances. Though not a big deal given if you play your slayer well, you'll rarely get a 4th swing.
Berserker:
Betting they did this class later, as the anims are much more refined, uniform and equalized across most races. Only 2 notable exceptions:
-Aman male: Swings his axe backwards on the third swing, and doesn't move forward.. Kind of a minor disadvantage.
-Popori - has a unique animation all around, doesn't seem to affect his range tho.
In general they are mostly balanced, tho Berserker in general seems to swing way too slow imo, don't see the reason for the disparity.. They need mana from basic attack same as slayers, should be the same speed. It's also reflected in there stats, there base attack speeds rated lower, so a simple tweak to that might be all it takes to equalize that.
Warrior:
Very well equalized. No notable advantages or disadvantages.
Popori and a cpl other races do have slightly unique looking anims, but movement and probably attack range seems about the same,
