Your doing something horribly wrong if your getting 50 seals in an hour. Can get more than that in 10 minutes simply afking in town and porting when someone posts a <pos> in linkshell chat then shouting for a group (or joining any of the hunt groups in PF)

Is it more effort than ST? No. More time consuming assuming you get one your 1st run? Yes. More time consuming than it will likely take? No

30% drop rate so will take you several runs on average to even see one. Then you likely have a 1/7 chance of winning (lets assume 1 person in your group is dumb enough to roll on the earlier loot).
