If BDM cruiser-spam is the issue, please just put a line in all the intel IDs saying that cruisers are restricted to the omicrons and edge worlds for exploration. I strongly protest leaving them out all-together.
The reason for removing cruisers, to balance the ZoI with ship choice, is a fallacy. The BDM and the LSF are the only active intel factions. This is due to their members and leadership, not just the ID. It is also only a fluke that the BDM is more active then the RM at the moment. This is due to RM leadership and members, again. BIS and Kempeti are dead while their navies thrive. The attractiveness of the ID isnt an issue.
Seriously though, I am fine with banning intel factions using cruisers for piracy. It is the omicrons and beyond that concern me.
