I've never done that, never seen that, and never heard about that til I read this post but........if you think its cheating you're an idiot.
Sounds like good strategy to me.
You can counter that by getting a lead early before they get their bubbles, then get your team (if organized) to just sit on the other side of the map away from them.
You don't get points it you don't get kills and that would draw them out away from their bubbles looking for you!
Don't cry about it, just play smarter!

It doesn't matter if you're in the lead by 3-5k a bubble team can ruin that easily, and it's hard to counter it since it's almost an endless amount of orbs which means, an endless amount of supers.

But if you stay over the other side of the map how will they kill you if they sit in their bubble? If your teams in the lead they'll have no choice but to leave their bubbles and come find you, and if your team is organized you can pick them off as they do.
