Whats good about Human Warriors?

A difference of a race is not that large, usually it goes up to which race you prefer the most.
However, if you do care about racial traits that much, a human gains a free medal that basically allows you to have 2 trinkets in PvP instead of 1.

Play whatever you like, and what you prefer.
And remember the most,
Enjoy the game!

human warriors are garbage compared to alot of the other classes, but if you really wanna stay as a warrior, once theyre higher level, they make excellent tanks, except now aday, pally's usually take up that role because they can also heal themselves.
