=== Fighting XP ===
This heavily depends on how much XP you can make in one hour and how valuable are the drops vs. your losses on degrades.

For a crude calculation, I assume I make 60 kXP in defense and 30 kXP in attack in one hour on polar bears and that the drops are 1k more worth than degrades/breaks.

Then we have:

  Time cost: 3600 sec = 3,6 kgc
  Drops - degrades =    1   kgc
  
  Cost per hour    =    2,6 kgc
  
  Att XP           =    30  kXP
  Def XP           =    60  kXP

If we split the costs by attack and defense, we arrive at 30kXP/1,3kgc = 23 XP/gc for attack and 46 XP/gc for defense.
