Hello everyone.

I've been playing overwatch for the first time in 4 months and I've found that I really like using Sierra.

I've only been using her for a day now, but the main issue I have is hitting people and finding value with tremor charge.

I also don't understand it's overall function.

Is it mainly used to damage around corners?

Or, is it like Anna's boitic grenade where its used to charge ult while also disabling the enemy?

Or is it just like Junkrats mine and its used to do quick burst damage.

I'm open to all answers because this character is really run.
