Glancing through it again the "A warrior droid's anthropomorphic body stands 6 feet 6 inches tall and it weighs 275 pound" doesn't need the "anthropomorphic body", but apart from that it's still fine.
Updating the 
Warrior Droid Working Draft.
	
		
	
	
		
		
			I think we could pretty much use the paradox break from the defective guardian droids.
		
		
	 
I was thinking of applying a slight tweak to the flavour text and 
possibly changing the table option 6's "self destructive spasms" to "berserkly attacking everything in sight".
Oh, and adjusting the stats so it doesn't fight like a Valet Droid, obviously!
How's this:
Defective Warrior Droids
A poorly maintained droid may become defective, causing it to act   erratically or even break down. This mostly happens to droids that have   been exposed to the weather, since rain or windblown particles   eventually wear through the droid's seals and corrode or jam delicate   inner workings. Droids that work indoors in stable climate conditions   rarely malfunction.
A defective warrior droid has the following changes to its statistics  block. Any statistic that is not listed is the same as a normal warrior droid.
Droid, Warrior, Defective
Initiative: +0
Speed: 30 ft. (6 squares)
Armor Class: 18 (-2 competence penalty, +2 Dex, +8 natural), touch 10, flat-footed 16
Base Attack/Grapple: +5/+8
Attack: high frequency sword +9 melee (2d6+6/19-20) or laser pistol +8 ranged (2d8 fire) or slam +8 melee (1d6+3)
Full Attack: high frequency sword +9 melee (2d6+6/19-20) or laser pistol +8 ranged (2d8 fire) or 2 slams +8 melee (1d6+3)
Space/Reach: 5 ft./5 ft.
Special Attacks: Defective droid, feat sockets, integral weapons, martial programming
Special Qualities: Advanced data slots, construct traits, damage reduction 5/adamantine, radarsight, radiospeech, robot traits
Saves: Fort +1, Ref +1, Will +1
Abilities: Str 16, Dex 14, Con —, Int 11, Wis 11, Cha 10
Skills: Listen +4, Spot +4, plus crystal card skills* (typically Climb +7, Jump +7, Search* +4)
* Many Warrior Droids substitute another Int-based skill for their crystal card's Search skill, such as Craft, Disable Device or Knowledge.
Challenge Rating: 4 [

A defective warrior droid gains the following defective droid traits:
Defective Droid: A defective droid has the following traits in addition to a standard droid's Robot Traits.
-  Faulty Circuits: A  defective droid's misfiring  circuitry give it a -2 competence penalty  to all its Dexterity-based  abilities (including AC, Initiative, Reflex  saves and ranged attacks)  and a -4 competence penalty to all Dexterity,  Intelligence, Wisdom and  Charisma-based ability checks and skill  checks.
- Paradox Break:   If a defective droid is presented with a paradox it must succeed at a   DC 10 Intelligence check or suffer a cognitive breakdown. An opponent   can force paradox check by making a Bluff or Diplomacy check (DC equals  20 plus the droid's HD) to  present the defective droid with an  anti-logical argument.
 A defective  droid must also make a paradox check if it in a situation  that isn't  covered by its programming (e.g. a defective security droid  that is  programmed to remain within a fortress would suffer a paradox  check if  it finds itself outside the fortress and has no instructions  as to how  to address the situation. If it succeeded on its paradox  check, it could  use its Radiospeech to ask for assistance, or set out  in search for the  fortress).
 Once a defective droid fails a paradox check, it immediately  starts  performing a random, nonsensical behavior determined by a roll  on the  Paradox Breakdown Table (see below). A paradox breakdown  continues  until the defective droid is repaired.
 A warrior droid that suffers a paradox break is more dangerous than most other types of droid. Its core function is to fight and kill, so if its safety circuits break down it is far more likely to harm any creature it encounters, including members of a creator or owner race.

Mite... Mite...".  Sages theorize this word means "error" or  "does not compute" in the  language of the droids' original creators.[/TD]  [/TR]  [TR] [TD]3[/TD]  [TD]The defective droid acts as if it were affected by a 
confusion spell.[/TD]  [/TR]  [TR] [TD]4[/TD]  [TD]The defective  droid obsessively tries to  perform its core function - a warrior droid may  select a random target and attack it, fighting any creature that tries to defend its objective; a miner droid  could try to dig to the center  of the planet; a valet droid might try to  launder any clothing it sees, and  so forth.[/TD]  [/TR]  [TR] [TD]5[/TD]  [TD]The defective  droid gets stuck in a "loop",  mindlessly repeating whatever actions it  took in the 1d4 rounds before  its breakdown. It does adjust its actions  to account for changes in the  circumstances. For example, a guardian  droid that got "looped" after it  charged out of its sentry post and  attacked an intruder would keep on  returning to its post, then charging  out to attack a square the intruder  was in. If there is a creature or  object in that square, the "looping"  defective droid attacks it with a  50% miss chance, since this is  equivalent to blindly attacking.[/TD]  [/TR]  [TR] [TD]6[/TD]  [TD]The defective  droid goes into berserk spasms, thrashing itself with its  limbs and randomly attacking anything near it. Every  round the droid moves 20 feet in  a random direction and does its slam  damage to itself as well as making a single melee or ranged attack against a randomly selected target. If the droid  succeeds at a DC 15 Wisdom check at the  end of its turn, it goes into  Emergency Shut Down to stop damaging  itself and its surroundings. The droid can destroy  itself if its spasms continue for long  enough.[/TD] [/TR] [/TABLE]
