I'm admittedly new to using seekers. I just started this past weekend. I've spent about 3 days farming because i love the "concept" of treasuring hunting.
Sucks to be you. Or maybe not, since you never experienced how much better it was before.
And it did indeed several of those things (good random thrash not as find, creatures, unique items etc.). But they snapped it's innocent little neck and replaced it with the seeker droid we have now.
@ Da_jon; From what I know, once an area is depleted another area on the same planet opens up. It's not CD-based and there are no 2 areas similataniously active on a planet. Also it thus can never be there is no active site on a planet. So that works fine, unless they changed that too post-2.2.3.
