As i had promised before here is my guide for all you spear warriors out there.
The spear warrior is the most balanced out of the 3 warrior classes.They have 3 ranged attack skills (spout,spouturen,deadly pierce) and the only ranged area effect skill (spouturen) for warriors.Deadly pierce is also the most powerful ranged skill for warriors.Making them the best for mobbing and killing higher level creeps(iv hunted succesfully at s2 at lvl 54).I dont think thats possible with any other charecter in this game.
Their hi level armour is also the best looking armour ingame(though thats a matter of personal preferance)personally i think their combat stance and the way they swing that spear also look awsome!!
ok ill start my guide now

Id like to add most of this information has been ripped from the sg forums , a lil bit of blogging,the guides ,sg official and unofficial sites talking to lulu and ingame chars.
STAT ALLOCATION
As i had said before the spear warrior is the most balanced warrior char
the stat allocation should be as follows
3 Str - 3 Dex every odd lvl. ie.1,3,5,7,9...........
4 str - 2 dex every even lvl. 2,4,6,8,...........
