Using any kind of filament (including abyssals) should
- have a 30sec spoolup delay before you actually jump. If you are aggressed within that time, the jump is aborted.
- on exit, a warpable beacon appears in the system where you land and stays active for 30 seconds.
- after jump, all cloaking devices are disabled for 15minutes, you can begin using them once your timer has expired. This timer is reduced to 5 minutes for Covert Cloaking Devices.
This would add a bit of risk to this magic teleporter at least, so if you decide to go into pochven, you are open for a hunt. Survive it and you can leave. And it would reveal deepsave-abyssalrunners pretty easily, adding more risk to chain-running the hightier sites, especially in HighSec.
