The Indar T would like to know your location to instantly terminate your for requesting something in direct opposition to its identity and being. Jokes aside, Last time I remember was about 4-5 years ago.
I think Lattice has rendered many locations useless. Also... Indar Bay Point, on the western side of Indar ? I remember fighting everywhere on Indar... a long time ago.
Peris Amp I've been at only last week. After reading this thread I contemplated a bit on Indar locations that are now completely locked and useless. Every side has about 3-5 locations where things just stop. In the north, we got Indar Excavation, Dahaka Amp, J908 and Mao. In the south west it's Hvar, Allatum, Vanu Archives and Peris (but often enough Regent Rock before that). In the south east the stations are Zurvan, Crimson Bluff and Rashnu. In addition, the middle with Ceres, TI and Crown is usually quite stable and everyone has to go around it, funneling everythign into the aforementioned end points.
