I and lots of others are having the same experience of inconsistency, when SG first came I would ping 130, then a few months later it just dropped to 100 and stayed there for another few months and occasionally it goes back up. I see this in other players ping more severely, megamite went from 60 to 150 over night and it stayed there for a few weeks then one day dropped again. For Karnage it was even worse, where he went from a playable 100 to 200 severely reducing how much fun it was for him. Though I have discovered that the ping I see for another is sometimes higher than the ping they see, even still something has changed from the stability of the IA days.
