You do realize Powerball runs on an ASSS server, right? This means that they've actually gone out of their way to inflate the population to match the side-effects of the other zones. PB only has 4 or 5 people in its zone, it's reporting 118. That's what, a 2300% to 3000% increase?   As much as I hate Hyperspace for also choosing to do this, someone did flat out admit in the last thread that PB had done this to give the zone a competitive edge. This pretty much indicates that arena sharing wasn't done for the sake of adding functionality, but rather to unnaturally inflate the population count, compete with Trench Wars (which also inflates population with bots), and use the feature inclusion as an excuse.   Hyperspace has demonstrated that the tactic works. And pretty much everyone in the last thread was dead-set against arena sharing, especially with the population inflation and skewing. No one has demonstrated that the feature brings anything to the game. Hyperspace did state it would stop if other zones did, but so far, only DSB has chosen to resolve the issue on their end.
