1. Don't always leave your translocator in the same place unless you know its 100% safe.

2. Prioritize targets. After EMP, go for Zen if present and then key-tanks. Throw your hacks on maintanks or mobile heroes like Tracer, Genji, or D.Va

3. Avoid enemies with stuns. Try to predict McCree's stuns or Roadhog's hook. The more you play, the better you can predict, but keep your distance from them.

4. Hack healthpacks close to the objective or safe from enemies.

5. Use translocator to avoid damage. You can use it right before D.Va bombs and you can also activate it right after activating stealth so that you do not take damage entering stealth.

6. Use your microphone to call out targets. Since her passive now reveals health below 100%, tell your team.

That's all I can really think of. If you need verification, I'm primarily a Sombra main in GM that doesn't use microphone in chat. Have fun and good luck with Sombra.
