What do you do in response to rogues sapping your team in Battlegrounds?

I've had this in a few games.

A few days ago, there were three rogues who were sapping the team.
And eventually decided to go for a kill, which didn't work out too well for them; I suppose the DK's and Pally have a lot of armor, and are over 3200 resilience.

Today, I had a pair of rogues chaining Sap and Distraction on the team.
I managed to get one of them out of stealth with the round-robin Death & Decay, laid down a large area...
And killed the rogue almost instantly as soon as I saw him.
But the other rogue was either out of the area or did the Cloak of Skill move.
He did a bunch more Saps on the team.
I eventually just left the one DK behind (ran around the side of the hill).
He decided to open on the DK, and I did a Death Grip and Heals...
He Vanished...
And did not engage again, but did spend the entirety of the BG sapping one or another of my toons.
The Death and Decays and Consecrate never pulled him out.

I don't mind so much being chain sapped, when I'm at an objective point, and holding it until it caps.
And I still kill random horde that come within Death Grip range.
And once in combat they cannot be sapped.

Still annoying when you're not in combat.
Especially if you're on the path or the Field of Strife, and not near anything strategic.



What is your approach to this?
