To fight

Gnats. One of the few mobs that do something of more dynamic when he teleports and use different attacks (360° aoe, cone, frontale etc) so you have to move your little feet and run around :P .. (95% of mobs in this game are tank and spank .. very very sadly mechanic in 2011 ) ..

To hate:

Prolly "humanoids" they are tough and with randomic attack.. they just use simple attack or they can spamm 2-3 ws at the same time >_> ...


To look

Cactuar! They are very well animated in particular the run animation
