I think the best warrior builds are 1h/2h/cleric, 1h/warlock, and my favorite 2h/cleric (I like better than 1h/2h/cleric because it is less sp costly).
2h Cleric-Crazy defense and extreme burst damage.
1h warlock- The debuffs and stuns while always holding a shield is very nice

Combined with all the 1h warrior skills.
Go 2h Cleric

1h Warlock is cool also if you know how to play well.
