We had the same issue - camping hole but by the time you scan, drop attack lines they were gone as 500 range makes CDs useless, this is if you do it as solo GB/frigate
You need 3-4 people, 2x snubs to cover both holes who have more than one chance at cd, + frigate/GB to kill em, ideally 2 at a hole, and that's for one enemy, if they bring lines/frigates in multiples they were just flying past us hah.
The profit is too high for the risk right now I'd say - won't lie that I had the urge to join the smuggling side too because it's so easy
Edit; I am talking about people who just don't watch player list and smuggle, slap on auto CMS - not even the legal metagamers and people with escorts
Edit 2: The issue is with the mechanics, CDs/CMS, armor to be clear, the event would be just fine pre patch, all ships have max armor now and get to minmax at the same time, while CDs seem to work worse Vs auto CMS
