Enough about AST! How do I use Emergency Tactics?

[Cynfael]

It was obvious going in to Heavensward that SE thought Scholar has some major healing muscle. But while we're brilliant at keeping the bar from going down, we're weaker in the "making it go back up" department. So, fellow book nerds, tell me how and in what situations you use Emergency Tactics? I've tried it out organically but it just makes me wanna spam Physick instead of fight the server latency. What say you, dead skill or hidden gem?

ET is mostly for turning Succor into Medica. Easy solution for restoring HP lost to a party-wide AoE without blowing your Indomitability.

ET+Adlo is for restoring a large chunk of HP without using a Lustrate stack. I don't find myself using this technique very often.
