The Abyss is good add to PVE as said several times.
So What is about a site that permanently has to escalate 30 NPC frigs
after every clear that been done and each frig has bounty like 100K
The rule is only frigs get in that sites and in high sec only.
For Supers Maybe to block it from normal cosmic but create
a similar farm tactic that spawn carriers like 10-15 and each one
has 10M bounty or even 50.
