Soldier if you are alone is all about noticing it and get Lucky to helix and hit her b4 you die.
The rest you said make sense, but i still think you have to rely on your teammates to heal you Quick enought and that doesn’t happens often in mid/low tiers.
You can’t get wraith while hacked but it is true. The thing is, most sombras will ignore reaper at all and go to isolated targets. Most reapers try to sneak in enemy backlines do some picks or just try to build up their ultimates.
A good/decent sombra can destroy a whole backline while reapers is just playing around.
