When you take too much damage, or if your locator is about to run out, port back, rinse, and repeat. It makes her a fairly decent hassler but her squishiness makes her difficult to play considering her locator is her only escape, while McCree has a roll and stun grenade, Pharah has her jetpack and knockback rocket, Soldier plays at ranged, Tracer has stupid mobility, and Genji is... well he's Genji.
Aside from that, good translocator teleports and stealth in mid-combat can help you get away to heal up and reposition. Throwing your translocator to higher ground or across the map, teleporting and stealthing will be able to get you out of trouble providing they haven't got a badass Hanzo or Widowmaker tracking you for a headshot.
Besides that? Not much else to it. She's one of those dip in and out characters like Tracer.
