Whow, how did we kill the Warlord in previous matches?
Reason for this is that mapper has set Warlord's ReducedDamagePct to 200 for the DamageType 'exploded' while the range of ReducedDamagePct should be 0 to 1.
The formula that calculates the damage is
Taking away a negative value from something means actually increasing it. So the Warlord only takes (positive ) damage from weapons without projectiles with DamageType 'exploded'.
But the name ReducedDamagePct can easily been understood as "give me a percent value" so I won't blame mappers here.
Fixed.
