South Korea:
Fissure or Gesture (MT)
Void or Zunba (FT)
Saebeyolbe (Tracer main)
Fl0w3r (hitscan and projectile)
Jjonak (better than RJH at Zen and Ana)
Ark or Tobi (Mercy/Lucio)

You don't seem to understand. Who's gonna play Lucio/Mercy? That's right. Noone. You need either Tobi or Ark or Gambler.
