How to beat Rogue Mage as WW/Disc

I think I have like 90% loss-rate vs Mage/Rogue as WW/Disc.

My general game-plan is to trinket ONLY after I've seen Smoke Bomb, as I'll be 100% dead if I end up in a Smoke Bomb w/o trinket.

The problems:
What do I do vs Sap heal + open on me without them using smokebomb? Some healers told me they want to stack up on top of each-other so Meteor breaks Sap. But in my mind that just means the Rogue is going to get free cheap shots on the healer. I feel like I have to insta-trinket the first stun regardless of Smoke Bomb and pop Wall + Incap on Mage and disarm the Rogue.

If I use my trinket, Rogues generally vanish, Mages do their alter time + 50 barriers shenanigans to not die, Rogue re-opens on me, Bomb, dead.
If I don't trinket I just die while disc is sapped.

If they somehow fuck up their opener and I live through the sap, its nigh-impossible to stay on the Rogue to keep him in combat. Frostnova on my pets and me, Tiger's Lust, Sheepspam + Frostbolt, Rogue waits out TP dot, restealth. It feels like they can do this as much as they want and eventually they kill something no matter how much they mess up.

Killing the mage feels like hitting a raidboss what with Alter Time, 300 barriers and the Rogue constantly re-stealthing.

Does WW/Disc just auto-lose against any Mage/Rogue with half a brain? I don't really see a winning strategy, what am I missing?
