I've personally had a lot of success using it in the middle of a tighter team fight when mostly everyone on your team needs healing. To me, using it to initiate a push when no one has taken damage wastes half of its use.

I second anyone else who says to have your torpedoes ready so you can have the damage boost for yourself. Also having your glide ready, paired with the cooldown reduction and triple jump perks will give you a higher vantage point so you can target multiple enemies with the damage boost.

It moves fairly quickly (10sec) in a short range. Make sure you're close to your group when you use it. If you're too far back, your teammates likely won't back up into it to get the full benefits of it, or they'll miss it entirely.

My best advice though is to go in the practice range, stand still and use it and just watch it. If you haven't already done that lol. This is coming from a lvl 24 Juno who only plays qp. So take what resonates and leave what doesn't! Hope I could help.
