.. Warrior is a nice build for pvp .. but u need to know how use it .. my GuildMaster D4rkLady( SET +5 FB , at least a normal set ) , know how use warrior and kill me in pvp ( i got a bower ), but i know a lot of warrior with really nice set, +7 , SOM who cant kill me in pvp =P cuz r noob .. make warrior only cuz all say " be warrior !! u kill all with warrior "
Second, the warrior is good for EXP, because it can easily access in party euro, but you will lure and I assure you that is not an easy thing and it is not funny.
Anyway for warrior best build is :
2 H : all Skills is the main weapon
1 H : as u want .. u can farm all skill , if u dont like farm , need only Passive skill and Shield Crush / Trush
Axe : Just skill for Bleed & Stun i dont remember name of skill .. xD
Cleric : PVP: Healing Cycle , Recovery Division , Phy & Mag Buff, Holy Spell , Pasive Skill of cleric for defence ( if u wear Light Armor ) , Integrity for leave Status from other player , like Bleed, Absolute Demage usefull for killing wizzard Full Buffed by a warrior ( only with Life Tournover

)
PVE: if u wanna be a cleric in a party Euro / Medusa / Roc / Job etc .. u need all skill for Heal + Healing Orbit , Group Reverse , STR buff INT buff , and all type of ress.
I'm sorry if I forgot something xD
Have Fun
