Yes and no. Players know that ships do Athena's and Merchants in the Roar. Merchants because of the high gold and rep but also because the islands are super easy to get to, you basically just keep sailing north and south while picking up and dropping off. Athena's because its super easy and quick to do. The only downside is the volcanoes if you are solo and if you are picking up loot.
If you throw up an Athena flag there is a chance if a Reaper ship lands they are going to go straight into the Roar, the percentage is about as relative as their starting position. The closer to the roar the higher the chance. Galleons Grave or Ancients the chances are pretty high they'll roll into the Roar to give it a glance. Reaper ships know that players do Athena's in the Roar because its way out of the way.
Gold Hoarders definitely safer in the Roar as no one really looks there for one, same with OoS. Merchants and Athena's is are the known factions that fly in the Roar. Players will only check roar for merchants if they already cleared out the server. Athena's again will depend on starting point of the reaper ship.
But yes, Roar is pretty good place to do stuff, wouldn't say "safe" but definitely out of the way and safer then most area's. HOWEVER, still keep eye on that horizon. Lots of players forget because they stay in the Roar for so long never seeing a ship that they just completely up and forget that there are other ships on the server. Even though its safer, you still need to be on the lookout. Safer doesn't mean absolute.
