Unclear Unit Stats in Warpedia

[Chazar]

The warpedia does not seem to answer the following questions to me. Does anyone know the answers?

• Kraken in a Swamp: has it just 4 fear, or a total of 6 (i.e. 2 fear always, plus 4 in swamps)?
  
• Does a ghost benefit from its own group ambush (i.e. has the ghost a total ambush value of 33% or just 25%)?
  For example, if I have the stack [wolf rider, ghost, ghost] do they have the respective ambush values of [36,41,41] or [36,33,33] or just [28,25,25]?
  
• Does a Valkyrie's Attack-Leadership stack with a Paladin's Leadership? (I would guess it is just the max of the two.)

Chazar,

1) 4 Total
2) Yes, [36,41,41] is the values the stack will have
3) No
