I believe the intent of your statement is getting lost in text form. No, I'm not 100% certain of the code change, it's been nearly a year. I remember we didn't have outposts clogging up our farms, now we do.
I'm not sure what the meaning of "move to more level appropriate areas" is supposed to imply either. My screenshot was just a simple example of a +7 level base triggering outposts. You are free to log into any world and view the same. I have a level 60 at the 15 POI line because we had just removed 26 bases from an enemy we knew hadn't logged into the game for a month.
There is no such thing as "appropriate area". Outposts are everywhere, it is physically impossible to create a level 55+ farm anywhere on any server that isn't in range of an outpost. Outposts are simply nuisances that refuse to go away that server absolutely no purpose after level 50. They also serve no benefit to the player, it's been proven they have lower return vs. CP/RT than camps but I also appreciate what they represent up through level 50. Beyond level 50, the only single benefit Outpost serve is to create havoc for players by causing camps to spawn farther away. Increased CP in turn lowers resource farming, slowing player growth.
Another solution would be to allow outposts up to level 68, triggered no different than camps based on player level. I say 68 because if you're making such a change, you should remove the camp level restriction as well and simply make all camps and outposts +/- 1 vs. the current code of +0/-1 with 65 cap.
