Video guide with a sample match: https://youtu.be/K7gOJXZiI4E

The Banners Fall support meta is Ying=Grover > Io> Lillith> SI Corvus> CM Pip> Healbot Rei > Mal'Damba > Jenos > Seris > Solar Blessing Furia > Grohk > Cherish Furia

Usually Lillith sees more play because she's a molotov despenser and my even have higher healing done than Io, but Lillith has such a higher skill floor.

Io being simple to play, being completely item free, and having one of the best survivability tactics of body blocking with Luna and your very own defender at the same time makes her matchups against flankers very favorable.

COMMON NOOB TRAPS IO PLAYERS FALL FOR

1- NEVER buy chronos as Io: you don't get more healing juice, you don't need more leaps, and keep luna alive by positioning her and moving her out of danger when needed, there's 0 legitimate reason to buy chronos even for the 16s cooldown of Luna respawning, waste of 1800 credits over a skill issue.

2- Don't deploy Luna in spawn: when you move her around, it takes much longer for her to move to your location if she was in spawn

3- Luna blocks people: yeah that's bad man don't block your teammates in doorways by moving luna into the door, also that's a bad spot for luna.
