Cloak/Dagger and Invisible Woman are lowkey a trash comp?

I know they are both seen as really good right now and both have the never dying ultimates, but i just feel like together they’re just so bad. I feel like im never getting any healing and i can’t ever play any dive characters because they both stay so far back so i wont get healed unless i go all the way back to the team. They only seem to work if your team is permanently bundled up, but even on dps i feel like im not getting healed because they always focus on healing tanks. its weird because just one of them and another support is usually very good but i think together its just bad.
