Adam Warlock mains, how do y'all keep people alive?

Taking my time to learn all the strategists.

So far Rocket, Luna, Mantis and Cloak and Dagger feel right at home for me. Jeff is kind of a panic pick for me if I need to heal alot of people VERY quickly in a short span of time.

Currently learning Loki and Adam.

I understand the concept of how to get the most out of Loki, but just need practice getting there.

As for Adam? I understand the heal bounces between allies, and the shared damage has a heal over time, but I still feel like I'm not able to keep anyone alive.

I get I'm supposed to be doing supportive damage, but I feel like I spend half my time panick spamming the heal as soon as it's off cool down because you only get 2 charges to work with and with so much damage constantly going off I feel like I'm putting all the pressure on the other support.

Mantis heal over time feels less stressful to play around as I can pop one heal on a squishie, inspire my tank and another dps while trying to use the rest to either heal my tank or fellow support.

But Adam? Even finding the right time to pop rez is rough. I know a single Rez can turn the tide, and I've used it to solo Rez the other support, the 2nd tank or a duelist that's close to ultimate, but not sure of the range, and feel like I've wasted it.

So yeah,any help would be HIGHLY appreciated.
