3 categories of classes 

1st - TANK ( like warrior , valkyrie ect )  high DP + grab + high crit ---------------) low AP + low mobility 

2nd- assassins ( ninja ,sorcc ect ) high evasion + high AP + high mobility -------) low crit + low DP

3rd- range classes ( archer , wizard ect ) high AP + high crit ------) low mobility + low dp + low evasion 

litle suggestion for my main , ( SORCC ) 

a lot of useless skills ( preaweakning ) i-frame is useless when we have much D-sync servers , ( counter 0 classes ) if u stay forward guard + super armor  sorcc player cant do nothing , u should put a lot of reset CC , because its hard to CC classes who know sorcc , i suggest a GRAB AREA for sorcc if you are near all super armor players can be CC ( with long CD )
