Here is a video that shows the difference in the racial auto attack animations for the melee classes. You can see some nice differences in the ranges traveled and swing arcs. The lancers also have some different damage lengths on there lances with the different races. Female amani lancer and baraka having the shortest and elin and elf having the longest. You can also see some examples of whats called “flinching” in tera. It occurs when auto attacking a player and it causes the target to do a flinch animation, there by causing a mini stun and can be done repeatedly assisting in locking down targets in pvp.
