Please think.
Today, before you make all the Alpha 2 orange while you figure out what to do with them, whats better?
1) No Orange spawns anywhere in game. All NPCs rubberband. They are farmable but will kill you if you get too close as a noob. Like it was in the old days.
2) Teleporting, Red here, Orange there, roaming here, Orange Observer Lvl III stashes that only kill the arkhe popping them while the sequer next to them grabs the 3 heavy mech cortexes unmolested. etc, etc.
What do you think is better?
What I would do ....
Alpha 1) All red, all static, set path roaming spawns
Alpha 2) All red, static mission spawns, set path roaming spawns, roaming Observers
Beta) All red, static mission spawns, all other spawns random roaming like Gamma
Gamma) All random roaming red spawns.
Give them a 1000 m chain.
You'll have dangerous and challenging islands. Setting the path ensures they cannot be pulled onto terminals, and most teles.
You will have a viable form of farming for income for players.
Its not that hard. You had it before and it was balanced.
