• A bodyguard (Shield one)

• A good corner
  
• Good equipment (down)

IF you don't have Outlaw DLC, use Mistic tribe

• Tribe: Warmonger
  
• Ability: Cursing

• Tribe: Outlaw
  
• Ability: Poison (recommend)

• Tribe: Warmonger
  
• Ability: Froze (This thing can stop ork from using his MOST IMBALANCE HEALING perk (hitting ground)

• Tribe: Warmonger
  
• Ability (2 types of cloak): +10hp per sec while burning BONUS immune to curse (or poison) by 90%

• Tribe: Outlaw
  
• Ability: Less damage against rage orks (not useful against cheaters, but still nice one), and +hp per kill

• Tribe: Warmonger
  
• Abilities: +HP while burning (with cloak is nice) and, your choise but better is incoming damage from friendly orks than damage resistance.

First is simple but harder, because cheater ork can accidentally hit u and his "No chance" can stop whole Invasion (in conquering other fortresses dominated orks or Ork slayer won't save you).
Second is timing required. And you need Lifeblood (Without this skill you can forget about this way)
IN First you need to fing corner so that ork can't kill someone with his best perk
4 Steps
1: Make cheater ork follow you (he won't, so hit him with hammer)
2: Summon your bodyguard and make him angry
3: Stun sometime cheater with hammer and DON'T Let him use his best perk
4: When green, dominate
Second
3 Steps
1: Go on roof or some far from point, but not so much
2: Just watch at allie orks hp (read Notice for explanation of this method)
3: When friendly orks are close to death, use Lifeblood
4: When green, dominate
Notice
When you far, orks can't use their super abilities or using class mechanics (like shield, ork becomes a simple warrior with sword, for optimisation
ALSO
for first you need red gems
for second green gem on dagger

They have all of those desert human boys bonuses (less damage from angry and more)
70% Of them can revive undead
