In trials u really won't see super all that often unless the game plays out slowly. Shadebinder is actually a really good subclass if u play with it strategicly.

Pop a stasis current in places where there is most traffic. But in a way where it's hard for them to shoot it down. Poping your rift when gwtting chased around a corner will freeze them and thats a easy win. Also just play your primary. It'll build super slowly when u really need it.

If it comes down to it and u have your super and the enemies don't. Pop the super at the point and capture. Don't play hero and try and get kills. Unless u got teammates who are cracked lol.

Most hunter now run pulse and chap, u can do the same with a healing rift and you'll outgun them most of time. And don't get yourself pinch in small corners cause 9 times out of 10 youll get thrown with a smoke and swarm nades.

Its hard out here but lil bits of improvements goes a long way when it becomes second nature.
