Xan hub- nerveta/arid/mitaar/vortex/12m, collector, instanced pande, gauntlet. Dustbrigade 1-2-3, db questline, inferno has tons of quests and dynas. RK has plenty of high level encounters from pvp tara to hollow island. There is plenty of things to do. If people honestly had so much fun in s10, they would still be there. It wasn't about the fun it was about the ease that vets could collect free credits and to an extent credit farmers working 24hour shifts making free credits pushing new players out of the instance.
The point is i've seen a lot of posts about how great s10 was for something fun to do. Bounties should be irrelevant to that fun and if those are honest statements there isn't anything stopping anyone from going there. Do I think bounties killed economy no, but I think bounties gave an excuse to players to stay there. The real money was and still is in lead bots for s10. Players are always looking for an edge and if they could make credits while farming to make even more credits from bots it was a win win situation and good use of time by killing 2 birds with 1 stone. Now it's easier to farm xan instances time wise.
