Also remember no grinding is a feature not a mistake
The problem is there's nothing to fill that void with. There is no activity to be done that keeps the server population filled between zc cycles.
Pvp is the only worthwhile thing doing right now (Until the dungeons start popping out T10 gear at least).
And sometimes even pvp isnt an option when you're outnumbered and your squad disconnects 1 by 1 because you keep losing.
In Counter Strike you can just go and play on public servers if your team isnt online for some real matches. In Street Fighter you can still go into practise mode and improve there if you cant find any real enemies. But in aop if there isn't any zc going on it's [??]
Well sure you can go and scavenge the core, but as Seki said in another part of the forum, with proper routes you can make 30k caps in 1-2 hours and that should be enough for at least a week and after that it's back to [??] again.
