just change the game mechanic in havoc, that pods dont steal roids, but transport them to a new owner
roids dont give ressources, you have to pay ressources as maintanance (your fleet beeing automatically sold if you run out of ressources)
that is what i would call havoc
P.s. any current setup is just dull to me - and i dont bother with havoc - might aswell remove it alltogether and me at least wont notice
