Warriors after big bang / chaos?

Disclaimer: I have NEVER played a Dragon Knight before, so wait for input on this build from those who have before using this (if they say it's good).

Swordsman

+1 Power Strike
+20 Slash Blast
+19 Power Strike
+10 HP Increase
+11 Iron Body

Spearman

+20 Weapon Mastery
+6 Weapon Booster
+20 Ground Smash
+10 Improved Fundamentals
+3 Iron Will
+20 Hyper Body
+20 Final Attack
+14 Weapon Booster
+8 Iron Will

Alternatives:
- Get Final Attack before Lv3 Iron Will (DPS build).
- Delay Ground Smash till after getting Hyper Body (Party build?).

Dragon Knight

+1 Dragon Fury
+20 Dragon Crusher
+10 Dragon Wisdom
+20 Dragon Blood
+19 Dragon Fury
+3 Sacrifice
+30 Dragon Roar
+11 Element Resistance
+17 Sacrifice
+20 Magic Crash

Notes:
- Lv1 Dragon Fury always outdamages Crusher on mobs of 4 or more, but the extra hits of Crusher are very useful when coupled with Wisdom's drain.
- Early Crusher for clustered mob destruction, followed by Dragon Wisdom for its drain effect.
-> After maxing Dragon Wisdom, spamming Crusher will make you almost unstoppable (3 extra hits = a higher chance you'll drain HP. Also a higher chance to crit).

Alternatives:
- Get Lv1 Sacrifice early on for bossing.
- Delay Dragon Roar till right before Magic Crash.
