Deepflow Rifts?

This event has ended now (I believe) but it was fun while it lasted, minus the length of time it took to scan down the rifts. You would park outside the rift (looked exactly like a wormhole), and start using salvaging modules on it, and then you’d pull out loot. You could get more loot if you used more salvagers, but if you used too much, you’d spawn bad guys. You had to find a balance. The ISK wasn’t great (especially if you take into consideration the time it took to find a rift, which you should) but it was a weird little event.
I appreciate the events like this, they liven things up a bit. I do think it was much more difficult to find rifts than I would have initially expected, but that’s OK.
Did you partake? Was it interesting? Let me know in comments, and as always, fly your way! o7
